A man broke his leg and suffered a bruised face in a mysterious attack in Banbury.

Two men were thrown out of Chicago Rock Café in Broad Street by doorstaff following an altercation inside just before midnight on Friday, police said today.

One of the men, aged 33, was attacked and received a blow to the head, leaving him unconscious for a few minutes and unable to remember what happened next.

He went to the Horton Hospital on Saturday, when it was discovered he had fractured his lower right leg as well as suffered bruising to his face.

A 26-year-old man from Bicester was arrested yesterday and released on police bail until July 5.
