DETECTIVES hunting a sex pest who committed a string of attacks on schoolgirls have released an e-fit of a man they want to question.

The assaults took place across four boroughs, including Barnet, over a 12-month period beginning last June.

Many offences were committed on a weekday between 7am and 9.30am as the victims were on their way to school in uniform.

The suspect approached some of them from behind, attempting to lift their skirts.

In some cases he touched their legs and in others he apologised before running off. None of the victims has been seriously injured.

Detectives from the Enfield Sapphire Unit are investigating a number of allegations and have released an e-fit of a man they want to talk to in connection with the attacks.

Detective Inspector Caroline Haines, who is leading the enquiry, said five more girls have come forward who believe they have been victims of the suspect as a result of media appeals.

He said: "While there appears to have been a break in offending over the school holidays, we would still advise vigilance, particularly around youth summer activities and events such as school youth groups.

"These incidents are clearly of concern and very distressing for the victims involved, but thankfully none of the offences has resulted so far in any injury.

“There is no evidence to suggest any particular schoolchildren are being targeted, but as a precaution we have made contact with all schools across the affected boroughs to inform them of the incidents."

He urged any parents with concerns to contact their Safer Schools team and anyone who may know the suspect to come forward.

The suspect is described as white, aged 30 years or older, of slim to medium build with possibly blue eyes. On several occasions he wore a black woolly hat.

Anyone with information is asked to contact the Sapphire Unit on 020 8345 4313 or Crimestoppers anonymously on 0800 555 111.
