Detectives investigating the rape of an 11-year-old girl in a supermarket toilet returned to t he scene of the crime yesterday, one week after the attack, in a bid to identify the teenager responsible.

Store workers helped officers distribute leaflets, featuring information about the offender, to shoppers who may have been at the Sainsbury's supermarket, in Leamington Spa, Warwickshire, at the same time last week.

Detectives have received more than 250 calls from members of the public, including a inmate serving a prison sentence, following an appeal for help from the victim's mother.

Detective Chief Inspector Adrian Pearson, who is leading the investigation, said some of the calls had provided officers with useful information.

Mr Pearson said: "Clearly many of the callers have had to make brave decisions in nominating suspects and thinking the unthinkable about people they know or associate with. I applaud them for their bravery and public spiritedness.

" The response to our appeals has meant a great deal to the victim and her family.

"I remain firmly convinced that the offender is either local or has strong local connections. His identity therefore will be known to the community.

"Please think carefully if you have any suspicions and call us. Every call is still vitally important."

Rewards totalling £30,000 have been offered for information leading to the conviction of the offender, who struck on Thursday, March 2, at the supermarket on the Shires Retail Park.

The leaflets feature an artist's impression of the offender and the distinctive jacket he was wearing. He is described as a white teenager with dark brown hair and red inflamed spots on his face.

He wore a black anorak-style hooded top with a red front and silver reflective piping.

Anyone who can offer information should call the incident room on 01926 415994 or Crimestoppers anonymously on 0800 555111.
