Wallace stepped aside from MasterChef in November after our initial investigation at the end of last year, when 13 people accused him of making inappropriate sexual comments.
The new claims come from people who say they encountered him across a range of shows and settings.
The majority say he made inappropriate sexual comments, while 11 women accuse him of inappropriate sexual behaviour, such as groping and touching.
One woman, who we're calling Alice, says Wallace took his trousers down in front of her in a dressing room, in what she described as "disgusting and predatory" behaviour.
Another says she was left feeling "absolutely horrified" and "quite sick" when he groped her.
