Police investigating nine sex assaults committed against women and girls in Hull have released CCTV of a man they want to trace.
Humberside Police said the victims, who were aged between 14 and 22, were attacked between 17 and 23 October.
They were all approached by a man on a bicycle who indecently assaulted them before cycling away.
Detectives are linking the attacks and want to speak to a man captured on CCTV on the city's Osborne Street.
The man involved in the incidents is described as aged between 35 and 45 and about 5ft 8in tall. He is believed to be balding with scruffy looking dark brown hair.
Anyone with information is asked to contact Humberside Police.
Det Insp Aiden Clark said: "These offences have been deeply upsetting for victims and are being taken very seriously by Humberside Police.
"We are keen to identify the man featured on the CCTV as soon as possible so he can assist us with inquiries."
