Teenage gang break man's skull in Abingdon attack
Six teenagers attacked two men near a churchyard in Oxfordshire, leaving one of them with a broken skull.
Three males and three females began a verbal altercation with the victims, aged 34 and 53, outside St Helen's Church in Abingdon on Saturday night.
They then attacked the men, punching and kicking them, before they ran off.
The older man is in hospital with facial injuries and a skull fracture, but the younger man was not injured.
Det Sgt Darren Cartwright said: "A number of investigations are under way to find the people responsible for this unprovoked attack, including establishing what the motive may be.
"One of the victims has sustained what may be serious injuries and is receiving hospital treatment."
In a separate attack on Saturday night, another man suffered a fracture to his face after being attacked outside Didcot Parkway train station.
The 41-year-old was walking past the station when a couple knocked him to the floor and kicked him in the head.
Police have arrested a 40-year-old man and a 33-year-old woman.
