Former Met Chief Detective Superintendent Sue Hill is here to appeal for our viewers help in solving some unsolved crimes, including an armed robbery and a woman who was assaulted on a night out.

CASE 1 - TEENAGER SUFFERS BROKEN JAW AFTER CONCERT
Detectives have released CCTV images of a man they want to speak to after a teenager was assaulted at an entertainment venue in Birmingham city centre. It happened at the O2 Academy on Bristol Road on the evening of 9th December 2011 where Professor Green had been performing. The 17-year-old victim had been enjoying a night out with a friend when, in a seemingly unprovoked attack, he was punched in the face by another man. A short while later the same man and another person attacked him for a second time outside the building. The victim was left with a broken jaw and required surgery. He also sustained superficial injuries to other parts of face, head and arms.

CONTACT: Anyone who has any information should contact Force CID at Harborne on the new non-emergency police number 101 or the independent charity Crimestoppers anonymously on 0800 555 111.

CASE 2 - ARMED ROBBERY
British Transport Police is appealing for information after a man was held at knifepoint, stabbed in the hand and robbed at Gidea Park rail station, near Romford, E London on Sunday 19th February 2012. The police said that at around 9pm the victim, a 25-year-old man from Newham, entered the waiting room on platform three at Gidea Park. Three men were already standing in the waiting room when the victim entered. They approached him and grabbed him suddenly, restraining him and holding a knife to his throat before demanding he hand over his belongings. One man held the knife to the victim's throat whilst the other two men searched him. Fearing for his life the victim handed over the two mobile phones he had in his possession, as well as £100 in cash. Following the robbery all three men left the waiting room, and ran to catch the Greater Anglia service bound for Shenfield. The victim remained at the station and reported the incident to police.

POLICE UPDATE: So far two men - a 31-year-old man from Romford and a 41-year-old man from Harold Wood - have been arrested in connection with the incident but investigators are now appealing for the public's help in a bid to identify the third man.

CASE 6 - CRIME VT - IAN NEWTION MURDER
At 8.05am on Mothering Sunday, 22nd March 2009 the body of Ian Newtion (45), was found in a pedestrian underpass at the Greenford Roundabout, North West London. Ian, aka Scoobie Santino, a delivery driver and singer from Fulham had received a fatal wound to the throat from a broken beer bottle. The motive behind Ian's brutal murder remains a mystery, but a possible robbery motive was a line of enquiry although none of Ian's personal property was missing when he was found (in the week preceding the murder a small number of robberies, where bottles were used as a weapon, were reported in neighbouring areas). A £20,000 reward is still on offer for information leading to the identification, arrest and prosecution of person/s responsible for the murder.

IAN'S MOVEMENTS: Ian had left 'The Scout Hut' community hall in Rockware Avenue at 07.45hrs after singing at a party in the early hours of the morning, and it is unlcear how he got to the underpass where he died. He was last seen alive by a jogger at the subway exit at approximately 07:55hrs and was described as looking agitated. Ian was wearing dark trousers, trainers and a dark jacket; he was also wearing a black rag-du (headscarf) on his head. Officers would like to trace anyone who may have seen him on the Greenford Road, or anyone who may have walked through the underpass area between 07.45hrs and 09.00hrs. It is possible that the suspect would have sustained a hand injury from the neck of the bottle, which was smashed in the assault. Anyone who has had a loved one come home with an unexplained injury, or covered in blood, or come home late on Mother's Day 2009 acting strangely, is asked to call the inquiry team.

CCTV: Detectives have released CCTV images taken from a petrol station near to the scene, at the time of the murder, which shows seven people that officers are keen to speak to. Detectives are also keen to trace a young girl in her teens they previously appealed for to come forward. She bought a large hydrangea plant at a florist's called 'Making Sense', inside Greenford Tube Station, at approximately 09.00hrs on the morning of the murder. It is believed the plant was purchased for her 'Nan'. It is likely she then got on a train at the station to go and visit her. She is described as white, approximately 16-20 years old, approximately 5ft 5inches tall and of athletic build. She has light coloured hair, which was tied back. Detectives are keen to speak to her as they believe she may have been in the underpass area, where the body was found, prior to visiting the shop and may have information that is vital to the enquiry.

CONTACT: Anyone with any information should contact the incident room on 020 8358 0400; if you wish to remain anonymous please call Crimestoppers on 0800 555 111.
