A man arrested in connection with two sex assaults in Peterborough is no longer part of the police investigation into the case.
One woman was sexually assaulted at knifepoint on a footpath near Rhubarb Bridge on September 30, while another was attacked on a footpath near the bridge on October 6.
An 18-year-old man was arrested in connection with both incidents - but Cambridgeshire police have said the man is no longer part of the investigation.
In the first incident, the victim, who is in her 20s, was walking towards Ivatt Way, when she was approached between 11am and 11.30am. She was approached by a youth who threatened her with a knife before sexually assaulting her. The victim managed to escape uninjured but was very shaken and upset.
The second attack happened at about 1.10pm when a 19-year-old woman was walking along the footpath which runs alongside the bowling alley, near to Rhubarb Bridge. A man approached her and slapped her on the bottom, grabbing her by the arms and snatching her handbag before running off towards Bretton.
Cambridgeshire police said they believed the two incidents, which happed a week apart, were linked.
The offender in both incidents is described as being of Asian appearance, in his late teenage years, between 5’ 8” and 5’ 10”, slim with short black hair and a small, scruffy moustache.
Two E-fits of suspects in the case have been released by police in an attempt to catch the culprit.
Peterborough City Council have also revealed CCTV cameras near the bridge were not working at the time of the incident after vandals had damaged a junction box.
A Cambridgeshire police spokesman said they were following a number of lines of enquiry following information given to them in public appeals following the attacks.
