Birmingham riot deaths: Calls for public inquiry

There have been calls for a public inquiry from the parents of three men killed in rioting in Birmingham in 2011.
Haroon Jahan and brothers Shazad Ali and Abdul Musavir died after they were hit by a car as they tried to protect local shops.
Eight men were cleared of murder in July 2012 - with the judge criticising the police investigation.
A report said a detective inspector was wrong to offer witnesses immunity from prosecution. The officer has since retired.
Tariq Jahan, who lost his son Haroon, spoke to Midlands Today's Mary Rhodes.
