The Independent Police Complaints Commission is investigating Kent Police’s response to information about a person of interest related to an investigation into a number of alleged sexual offences.
On 7 February John Williams, 46, pleaded guilty to 11 counts of sexual assault between 9 November 2010 and 2 August 2013, and an indecent assault and attempted theft of a handbag in 1991. He asked for 16 further sexual and theft offences to be taken into consideration.
The allegations had been under investigation by Kent Police since November 2010 and were linked across a number of operations.
Mr Williams was identified as a person of interest to the investigation in October 2012 after a member of the public responded to an e-fit of the suspect released in the local media.
Kent Police referred the case to the IPCC on 2 January 2014 after concerns were identified regarding the handling of an action to take a DNA sample from Mr Williams in November 2012.
Mr Williams was interviewed by Kent Police in September 2013 and a DNA sample was taken which matched him to sexual assaults in 2012.
He was later arrested in connection with the sexual assaults and charged with offences dating back to 1991. Two of the attacks took place in the summer of 2013. Both victims have been informed of the IPCC investigation.
IPCC investigators have served gross misconduct notices on two officers, a detective chief inspector and a detective constable, advising them their conduct is subject to investigation.
