Susanna Reid once chased after an armed mugger who slashed her handbag with a knife.
The "Good Morning Britain" presenter has opened up about the "traumatic" ordeal - which happened in Brixton, South London - as part of a discussion about bystanders filming a violent assault on a female police officer instead of stepping in to help.
Speaking on the ITV breakfast show, she said: "I got mugged once by a guy with a knife and my instinct was to run after him.
"It's not rational and obviously it was dangerous, but he got scared and dropped my bag.
"He slashed my bag off me and cut through my coat. I was incandescent. I ran around 100 yards after him. He ran up over a bridge because I was absolutely furious.
"I followed him up over the bridge and saw him shaking out my bag. He ran off. He took the cash out of my bag, but I got the bag back, which was obviously broken, and my phone and my keys."
Unfortunately, the criminal wasn't caught after Susanna wasn't able to pick him out of a lineup.
She didn't get a good look at the man when she chased after him, because she was "acting on instinct" rather than making a conscious decision.
She added: "I think it was red mist. I wasn't really looking at him. I was just acting on instinct
"I don't think I would have chosen to do it, it was because I was propelled to do it. I just wouldn't let him get away with it."
