TV weather presenter Fred Talbot has been arrested by police investigating allegations of historical child sex abuse at a Greater Manchester school.
Officers are examining claims of abuse at Altrincham Grammar School for Boys in the 1970s and 80s.
Mr Talbot was arrested on suspicion of three counts of indecent assault and four counts of inciting a child to commit acts of gross indecency.
The 63-year-old was a biology teacher at the school at the time.
A police spokesman said: "The offences relate to his time as a teacher at the school between the early 1970s to early 1980s, while the four victims were pupils."
Mr Talbot's agent, Dave Warwick, said he had "no comment" to make about the arrest.
Police raided the presenter's home in Bowdon, Trafford, on 11 December. According to his Twitter account, he was abroad at the time.
A police spokesman said: "Since allegations were made to police in December we have made good progress with this investigation and with tracing and speaking to former pupils of Altrincham Grammar school.
"However, as part of our ongoing enquiry I am eager to trace anyone who attended the school between the early 1970s and 1980s, who feel they may have information to assist the police investigation."
Mr Talbot, who worked for ITV's Granada Reports programme, is best known for his work on the ITV programme This Morning when it was hosted by Richard Madeley and Judy Finnigan.
He presented his weather reports using a large floating map of the British isles at Liverpool's Albert Dock.
