Tariq Jahan, from Birmingham, went on national television and appealed to people in his community to stop rioting. His appeal came just hours after his own son and two friends had been mown down and killed by a hit-and-run driver.
Mr Jahan - who was given the Pride of Britain Award in 2011 for his actions during the riots - says his own tragedy has compelled him to help other suffering communities.
"I know the pain of losing a child like so many people in Syria now," he says.
"Human Appeal is currently on the ground helping the innocent people who've been caught up in this terrible atrocity. After hearing about the work Human Appeal has been doing, I knew I had to help."
A quarter of the Syrian population is now displaced and over 70,000 have been killed.
