Four people arrested in connection with a street attack on a 17-year-old boy have been released on police bail.

Sam Morley, of Thirkhill Court, West Bowling, suffered serious injuries when a gang attacked him in Hopbine Avenue, West Bowling, at 10pm on Tuesday.

His skull was fractured in four places and he was left with internal bleeding behind his eyes. Police believe the attackers hit him with pieces of fencing.

Three females, aged 18, 17 and 15, and a 43-year-old man, were quizzed by police and have been bailed pending further inquiries.

Mr Morley, known to his friends as Little Sam or Manthra, was discharged from Bradford Royal Infirmary today.
