Caroline Flack, a well-known television personality and former host of the ITV television series “Love Island” and other shows in Britain, died on Saturday in London. She was 40.

ITV confirmed her death. A lawyer for her family said she had died by suicide and was found in her home, The Associated Press reported.

In 2015, Ms. Flack began hosting “Love Island,” a British dating-reality show on which the public voted off “islanders” until one couple remained.

She was replaced as host in December after being charged with assault from an episode involving her boyfriend, the tennis star Lewis Burton, The Guardian reported.
