Police will hand out more than 9,000 letters to residents in Rusholme as they look for missing mother-of-six Kimberley Brown.
IPCC investigating whether police officers misled families over the disposal of human remains from victims of Harold Shipman.
Two officers from Greater Manchester Police will face a gross misconduct hearing over the death of a PC during a training exercise.
The IPCC said the GMP whistleblower has made a number of allegations including cronyism among senior officers, failure to follow correct procedures, failure to investigate complaints properly and corruption.
Following an IPCC assessment, all other allegations outside of the three investigations have been returned to GMP for the force to deal with.
Officers whose actions will be investigated range from the rank of constable up to GMP’s Assistant Chief Constable, Terry Sweeney.
He was seconded to work on Operation Resolve, the police investigation into the Hillsborough disaster, but has now returned to GMP.
– Jan Williams, IPCC Commissioner
These are serious allegations and the gravity and nature of the allegations, and the fact that they are made against senior officers within the force, means they must be investigated independently.
We will also look at the wider organisational response by Greater Manchester Police in each of these investigations.
We know that the families involved will have been through very distressing times, and we will be sensitive to this as we conduct our investigations.
The Independent Police Complaints Commission has launched three investigations into Greater Manchester Police following allegations made by an officer serving in the force.
The three investigations will examine:
- Whether GMP officers misled families and the public when human tissue from victims of serial killer Harold Shipman was disposed
- Claims that an investigation into alleged sexual abuse was poorly handled and the alleged failings covered-up by GMP
- The actions of a Detective Chief Inspector over alleged unauthorised bugging of a GMP office. The force has told the IPCC that this bugging did take place.
Police in Greater Manchester have received over two thousand pieces of intelligence relating to child sexual exploitation in less than a year.
Detectives say the horror of the Rochdale grooming case means the public is now more likely to call them with tip offs.
The 2,286 separate alerts from members of the public, observations by police, social services, schools and other agencies came in just ten months up to January this year.
The force says it reveals a high level of public awareness.
The Chief Constable of Greater Manchester Police says his officers are spending more and more time helping vulnerable people with mental health issues.
Sir Peter Fahy says 'it's a scandal' that officers' time is being tied up dealing with people who need psychiatric help.
Meanwhile; the families of people with mental health problems say they're now expected to do the jobs of trained professionals.
NHS England says no funding had been cut for mental health services and that a five year plan is now underway to provide greater support for mental health services.
Health minister Norman Lamb has told ITV News it's unacceptable that mental health loses out within NHS budgets.
He claims there is an institutional bias against mental health.
Sir Peter Fahy says Greater Manchester Police is facing more pressure because of the growing problem of mental health among the public.
He says his officers are stretched enough, and aren't trained to make mental health assessments:
The Chief Constable of Greater Manchester Police says dealing with mental illness has become the number one issue for his front line officers - and the problem is getting worse.
Sir Peter Fahy said "It is a scandal that police officers are tied up and they're not available on the street to serve the public because of huge delays at A & E. Often officers are forced to spend hours waiting with patients at hospitals waiting for consultants to make a decision or find a bed."
Despite his officers not being trained to make mental health assessments Sir Peter told Granada Reports they are being called upon to carry out the roles of professionals and that it is now taking up a huge part of police work.
Greater Manchester Police are investigating a scam where fake charity wristbands have been sold fraudulently.
The scam relates to a missing person charity called 'Social Alert Me' which uses social media to send out alerts regarding missing people.
Detectives say between September 2013 and December 2013, the charity's wristbands were replicated and sold to the public under the guise of being a charity; however the money was never deposited with the charity.
Police are warning the public of the scam and asking anyone who believes they have bought a fake wristband to contact police.
Detective Constable Chris Clarke said: "It is believed that up to 5,000 fake charity wristbands have been produced and sold to unsuspecting members of the public.
"We would ask anyone who has bought one to get in touch with police.
"Social Alert Me (SAM) is a small charity but a genuine organisation which aims to get information out quickly about missing people using social media. If anyone wants to buy a genuine SAM wristband they can do so via the link on their Twitter account."
The genuine wristbands include the website address and #SAMAlert whereas the fake wristbands just have 'Help Missing Children' printed on them.
Two men, aged 32 and 31, have been arrested on suspicion of fraud by false representation and have been police bailed pending further enquiries.
Social Alert Me can be contacted via Twitter @socialalertme #SAMAlert or Facebook by searching Socialalertme or visit their website at www.socialalertme.com
