The home of TV weatherman Fred Talbot has been raided by police as part of an investigation into historic sexual abuse, sources said.

The alleged offences relate to sexual abuse in the early 1970s while the victims were pupils at Altrincham Grammar School for Boys.

Greater Manchester Police said a number of warrants were executed on December 11 but no arrests have yet been made.

Police sources said three separate complaints about alleged historic abuse had been received.

Talbot, 63, a former biology teacher at the school, is understood to be away from his home in Bowdon, Greater Manchester, and is out of the country.

He is best known for his colourful appearances on the weather map for ITV's This Morning programme when hosted by Richard Madeley and Judy Finnigan at Liverpool's Albert Dock.

Talbot remains the weatherman on the station's North West regional news programme Granada Reports.

On December 10, he told followers on his Twitter account that he was sailing in the Atlantic Ocean for six days after leaving Madeira.

Six days later, he posted: "Land at last. After six days at sea St Kitts."

Police said their investigation was prompted following media reports of another probe into historic sexual abuse at a Catholic boys' school in Altrincham.
