Picture: Google maps Source: Supplied A YOUTH headbutted a 67-year-old man knocking him to the ground in Mona Vale last night in a vicious and unprovoked attack. The victim cut his hand on broken glass as he tried to break his fall and was left with a swollen face from where he was hit. Police said the local man was walking along Park St near the Mona Vale Hotel when he was approached by two youths about 9.15pm. One asked him for a light but when the older man reached into his pocket, the youth headbutted him, causing him to fall and injure himself. The two youths then ran away and were last seen running past the entrance to the Mona Vale Hotel and towards Darley St. They were described as being about 18 years old, of Caucasian appearance and tall, with one wearing a blue hoddie and one wearing a black one, and both wearing tracksuit pants. Northern Beaches duty officer Insp Graeme Pickering said the 67-year-old man, who lives at Mona Vale, sustained slight swelling to his face from the headbutt and a minor cut to one hand from the piece of broken glass when he fell to the ground. "This was a totally random attack," he said. It came out of the blue. The man did not recognise his attackers. He said police patrolled the area but didn't find the youths and have now launched in investigation into the attack. He urged anyone who witnessed the incident to call Dee Why police station on 9971 3399 or Crime Stoppers on 1800 333 000.
