A 21-year-old man was stabbed in the back as he walked home in Morecambe on Saturday.
The incident happened about 1am on Carlton Street when the victim was approached by a man who angrily accused him of breaking his window.
When the victim denied doing anything wrong the offender punched and kicked him and stabbed him in the back causing a deep wound which required surgery. He then fled in the direction of Woodhill Lane.
The attacker was white, aged in his mid-20s to early 30s, of stocky to muscular build and around 5ft 10ins tall.
He had short dark cropped hair which was shorter at the sides, and his nose is described as being wider than average. He spoke with a northern accent and was wearing a light grey t-shirt and dark bottoms.
DC Brian Shepherd from Morecambe CID said: “This was a sickening attack on a young man who was simply walking home. The victim sustained a deep stab wound which only narrowly missed his vital organs so we could have been dealing with a much more serious incident.
“We need the public’s help to catch the man responsible. Anyone with any information should contact DC Brian Shepherd on 01524 596712 or 01524 63333 quoting log lc-20110924-0147 or Crimestoppers on 0800 555 111”
Police are also keen to trace the occupants of a small silver car which was seen in the area of Carlton Street and Woodhill Lane around the time of the offence.
The car was being driven by a young, blonde haired woman and there was a stocky dark haired man in the front passenger seat who was on his mobile phone. Police say they could be key witnesses.
