A man was attacked after confronting a group of yobs who hurled an egg at his window.
The 53-year-old went outside his home on Sandygate, Wath-upon-Dearne, to challenge a group of 20-30 youths gathered outside.
Police said he chased two of them away from his home before being confronted by a larger group.
A South Yorkshire Police spokeswoman said: “The man sustained bruising, cuts and broken bones that required hospital treatment.
“The group of both males and females, aged approximately 14 to 17-years-old, had fled the scene before police arrived.”
