Law and Order: UK: Help

Crime drama series. When a former footballer is beaten to death on a London street in what looks like a robbery gone wrong, investigations lead Ronnie and Matt to Mike Jones. He was seen in the area at the time of the murder, has motive and is linked to the murder weapon. Protesting his innocence, Mike points the finger at a well-known East End gangster who he claims he saw at the scene of the crime. At the trial James Steel is up against eccentric defence barrister Jason Peters. Witness intimidation, false plea bargaining and corruption stand in the way of the truth but in the end, will the decency of one good samaritan be enough to finally put the murderer away?
