CCTV of man released in Oxford stabbing probe
CCTV footage of a man who might have "vital information" about the stabbing of an 18-year-old has been released.
The man was stabbed on Oxford's Cowley Road on 9 May. Thames Valley Police has already arrested four men on suspicion of attempted murder.
The force has appealed for the man in the image to come forward as they believe he could help secure a conviction.
The men who were arrested, aged between 18 and 35, have been bailed.
Officers also want to speak to two drivers - one of a white van and another of a white hatchback - who were both seen on James Street on the day of the attack.
