Comedian Michael McIntyre was robbed by two men on a moped while he was parked outside his children’s school, his publicist said.
The men smashed his car windows with a hammer on Monday before taking his watch and fleeing, it was reported.
His wife Kitty said the star was “fine” after the robbery at about 14:00 BST on North End Road in Golders Green , north-west London.
Asked if they were concerned about the family’s safety, Ms McIntyre told “no”.
“The victim was stationary in his automobile when two males on a moped smashed the car windows with a hammer before stealing property, ” the Metropolitan Police said in a statement.
Police told no traumata were reported and no apprehends have been attained.
Local residents spoke to BBC Radio London in accordance with the robbery.
One woman, who did not want to be named, said: “I’ve lived here for years, and usually the trouble is down the other objective of the road towards Hampstead.”
She said Hampstead seemed to be increasingly targeted because it is a wealthy area.
But another resident, who has lived on the leafy road for 30 years, told: “I’m not worried because I don’t wear a Rolex and don’t drive around in a Range Rover.”
McIntyre is a stand-up comedian and host of Saturday night entertainment series Michael McIntyre’s Big Show.
His UK tour in 2012, during which he played to over 700,000 people in 71 venues including 10 nights at London’s O2 arena, reportedly earned the comic PS21m.
McIntyre has also been a judge on Britain’s Got Talent and has appeared on numerous quiz panel shows.
Police said the suspects stole “several items of property”.
One man has been arrested on suspicion of robbery.
