British television presenter Jim Davidson was on Wednesday rearrested by police investigating sexual abuse allegations, media reports said.
Metropolitan Police said officers from Operation Yewtree, set up last year in the wake of claims of abuse against late BBC presenter Jimmy Savile, said a 59-year-old man had been "further arrested on suspicion of sexual offences in connection with further allegations".
He was initially detained on January 2 along with a 53-year-old man.
Scotland Yard stressed that the arrests were not connected to the specific allegations made against Savile.
Davidson, 59, found fame as a bawdy stand-up comedian in the 1970s before going on to host BBC's prime-time snooker-based game show "Big Break" during the 90s.
The presenter, once named "Britain's funniest man", has spoken about his battles against alcoholism and admitted to violent attacks against his former wife.
Savile, who died last year aged 84 after a long career in British television and radio, has been accused of abusing around 300 victims over a 40-year period at a number of institutions, including the BBC and three hospitals.
The scandal has snowballed since claims that Savile molested underage girls were aired in a television documentary last month, leading to the arrests of singer Gary Glitter and comedian Freddie Starr.
