Police have launched a hunt in Birmingham for a man thought to have made thousands of indecent phone calls to primary schools and nurseries across the UK.
Dozens of female members of staff have reported to officers their concerns after receiving “extremely unpleasant and disturbing” phone calls.
Detectives hunting the pest, who is also thought to have phoned dental surgeries, have tracked the origins of some of the phone calls and believe the caller may live in the city.
They also think he drivers an old-style blue Ford Fiesta.
Today they released CCTV footage of a man they wanted to trace in connection with their inquiry.
Officers on the case revealed that the calls first started on June 8 this year.
A total of 15 different mobile phone numbers have been used to make the calls - and 4,000 calls have come from just two numbers alone.
Northamptonshire Police launched the inquiry, which now also involves 22 other police forces, after calls to schools in the county.
Det Con Katie Broadbent, who is leading the investigation, said the calls were not one-offs, and were being made on a daily basis. Police said the offender seemed to be targeting premises with predominantly female staff. So far, about 90 people have come forward to report the calls but police believe there are victims who have yet to do so.
Det Con Broadbent said: “Receiving a call of the type this man has been making is an extremely unpleasant and disturbing experience for the women involved,” she said.
“We urge anybody to contact police if they have any information whatsoever about these phone calls, if they think they have received a call but not reported it, or if they think they may know this man.”
Anyone with information should call Northamptonshire Police on 03000 111 222.
