Police investigating five needle attacks on women in Birmingham have had reports of six further attacks which could be linked to the same suspect.
Officers said the six fresh reports date back six months.
A new CCTV image of a man police believe could help them track the suspect has also been released.
It was taken about 03:00 BST on Sunday 3 November, when a 30-year-old woman felt a sharp pain in her thigh – later confirmed as a puncture wound.
A picture of the suspect was released by officers on Friday.
Det Insp Julie Woods said: “We have received several calls with information following the appeal on Friday and are currently following these up.
“We have also received reports of six further attacks going back over the last six months which could possibly be linked to the same suspect.
“However, we are still keen to hear from anyone who has any information about these incidents and who recognises either of the men in the CCTV images.
“These are strange offences and the motive at this stage is unclear, but we do not underestimate the anxiety and stress that the attacks can cause.”
Police have increased patrols in Broad Street and around the city centre.
