REDBRIDGE school children are warned to be on their guard as police hunt a notorious sex attacker.

Detectives investigating a number of sexual assaults on at least 24 young girls across north-east London - including Redbridge - are appealing for information.

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

Two assaults took place over the past 12 months in Redbridge, ten in Enfield, nine in Barnet and a further three in Waltham Forest.

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.

Officers from the Sapphire Unit at Enfield are leading the investigation and inquiries continue.

Two men have been arrested but eliminated from the enquiry.

Detective Inspector Caroline Haines, who is leading the enquiry, said: "As a result of previous media appeals, five more girls have come forward saying that they believe they were victims of this man in the past.

"We have a new E-Fit and appeal to anyone who thinks that they might recognise this man to contact us as soon as possible. I would also appeal directly to the suspect and urge him to contact us.

"Whilst 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.

"If any parent or guardian has concerns, we would encourage them to contact their Safer Schools officers. Anyone who believes that they have been a victim should contact the investigation team."

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