A teenager was assaulted in the street during an unprovoked attack in Corby.
The 13-year-old was in Wick Close just before 8pm on Thursday, October 29, when he was kicked and punched by another teenage boy.
The young boy had seen the older teenager earlier in Butland Road where the older boy had challenged him to a fight - but he walked away.
The attacker was described as being aged between 15 and 16 and was slim with short brown hair.
He was wearing a black hoodie and black tracksuit bottoms and was among a group of other boys.
Police are appealing for witnesses or anyone with information to contact them on 101 or Crimestoppers anonymously on 0800 555111.
