A fire broke out at the center at 11.40 p.m. on Sunday before it was tackled by more than 30 firefighters.
A mosque has been severely damaged in a suspected arson attack.
Mr Oladimedji said: "It has been seriously damaged - the police won't let us in".
GMFRS confirmed: 'We were called at 11.43pm to Droylsden Road in Newton Heath to reports of a fire. We sent five pumps to the scene and an investigation is now underway'.
Monsurat Adebanjo-Aremu, secretary of the centre, said people have urinated outside and two pigs' heads were once thrown into the mosque during worship.
It is thought that no one was inside the building, in north Manchester, at the time the fire started and no injuries have been reported, according to The Telegraph.
A spokesman for Greater Manchester Police (GMP) spokesperson said: "The fire is being treated as suspicious and a joint investigation has been launched by GMP and Greater Manchester Fire and Rescue Service [GMFRS]". Moreover, a minibus - the centre uses to gerry young and elderly visitors to the mosque - was destroyed in an arson attack in 2014.
Flames appeared to come out of the roof and lit up the sky and surrounding buildings.
