TV star Jack Osbourne, the son of rocker Ozzy Osbourne, helped catch an alleged mugger in London by wrestling the man to the ground, a source says.
The source said Osbourne immediately chased the unidentified man and tackled him, enabling other citizens to help him restrain the suspect until police arrived.
The 22-year-old Osbourne told the News of the World his impromptu crime-fighting decision was merely the "right thing to do" in the circumstances, the Telegraph said.
"I could see the girl was in trouble; it just felt like the natural thing to do. I'm glad it turned out OK," the former star of the reality TV series "The Osbournes" said.
