The home of Eric Morecambe’s widow was broken into while she attended the unveiling of a statue of her late husband, the BBC understands.
Joan Bartholomew, 89, was in Blackpool at the time burglars targeted her home in Harpenden, Hertfordshire.
Police said items of jewellery, including rings and watches, were stolen at some time between Thursday and Sunday.
The statue of Morecambe and Wise marks their first stage appearance together.
Mrs Bartholomew’s son, Gary, who was also at the unveiling on Friday at Blackpool’s Winter Gardens, told the Lancashire newspaper The Visitor that thieves may have been aware of his mother’s trip via social media.
“They must have known she was away,” he said.
“There wasn’t masses of damage. My mum is a very realistic person, she doesn’t like to make herself into a victim. It’s just the way it is.”
