ROBBERS battered Shaun Chapman and threatened him with a handsaw blade during an "unprovoked and vicious attack".
The 21-year-old was stamped on, punched and kicked by two teeners in a Stroud subway at 7.30pm on Friday.
He was taken to Gloucestershire Royal Hospital with facial injuries after the robbers tried to steal his mobile phone in the underpass in Dr Newton's Way, Wallbridge.
The former Maidenhill School pupil said one of the pair approached him and said "excuse me blood, you've got something for me" before demanding his phone.
The Tesco worker said: "I shoved one of them away and the other pulled out the saw. A couple of punches were thrown and I tried to run into town but they caught me in the subway.
"They had me against the wall and were punching me in the face. I tripped over and I was on the floor and I could see them trying to kick me in the face.
"I knew I just had to get away and my face was battered. I got up and I saw one of them coming at me with the blade. I grabbed it and managed to break the blade and just ran."
Shaun went to the Lord John pub, where he was heading to meet his family for a birthday party.
Inspector Tony Fisk, from Gloucestershire Police, confirmed officers were investigating what he described as an "unprovoked and vicious attack".
One of the robbers was 6ft, of medium build, with acne on his face and short wavy black hair. He wore a black McKenzie jacket with white Nike Air Max trainers. The second was over 6ft, of a stockier build, with short dark hair and was wearing a black McKenzie hoodie.
Anyone with information can call police on 101 quoting incident 398 of February 1.
