A rapist from Poland who launched a vicious unprovoked attack on a man with learning difficulties, just 48-hours after arriving in Britain, has been jailed for 12-years.

Damien Pankiewicz, 37, approached the 52-year-old victim as he stood at a bus stop in Brixton, south London and began repeatedly punching him until he fell unconscious to the ground.

He then grabbed him by the neck and dragged him into the road in front of an oncoming double decker bus, which managed to stop just in time.

The victim suffered bleeding on the brain, a broken leg and broken ribs during the attack and was in hospital for three weeks.
