Stephen Timms, said some of the constituents he spoke to on Monday were "concerned" about the unrest and campaigner's claims that 25 year old Edir Frederico Da Costa was brutally beaten after police stopped his car.
Timms explained: "I think it's right to pray for peace on the streets of our borough.
"Much of the demonstration yesterday was peaceful but towards the end of the day it turned violent - that is in nobody's interest."
Protesters were demanding justice for Mr Da Costa, who died on June 21 after a traffic stop.
One male officer suffered facial injuries and a female officer sustained head injuries as individuals threw bricks toward police and set fires at the scene in Forest Gate, east London, Scotland Yard said.
Campaigners claim Mr Da Costa's neck was broken and he was "brutally beaten" after the car, containing three people, was stopped in Woodcocks, Beckton.
Protesters, some carrying Black Lives Matter posters and others with homemade placards which read "Justice for Edson + How Many More???", marched from Forest Gate to Stratford on Sunday.
However the Independent Police Complaints Commission (IPCC), which is investigating, said a preliminary post-mortem on Thursday indicated there were no spinal injuries caused by police.
Timms told Premier he had spoken via social media to some of Mr Da Costa's family and said he hoped to meet with them in person to ask them about the protester's accusation.
He said:"If there is evidence there then I will certainly pursue it and do my level best to get to the bottom of what really happened."
He also urged Christians to pray that "The truth will become known - that we will find out exactly what happened and that everyone who's concerned about this incident will learn what the truth was about what really happened."
