JLS singer Oritsé Williams' €3.4 million mansion was gutted in an inferno which British police are treating as suspicious. 

Approximately 70 firefighters were called to tackle the massive fire which started on Tuesday afternoon at Williams' south London property, destroying most of the roof and the second floor. 

The devastating fire comes just one week after the singer was found not guilty of rape after a nine-day trial at Wolverhampton Crown Court. 

While the cause of the fire is yet to be determined, police have confirmed that they are treating it as suspicious and are launching an investigation.

A spokesman for the Metropolitan Police said: "Police were called at 16.39pm on Tuesday, 4 June following reports of a fire at a residential address in Spout Hill, Croydon. Officers attended with LFB [London Fire Brigade]. There were no reported injuries. 

"There have been no arrests. At this stage, the incident is being treated as suspicious. The cause of the fire is under investigation."

The six-bedroom house was once the beloved home of comedian Ronnie Corbett, who lived there for more than 30 years. 

Williams purchased the property in 2013 with his then-girlfriend AJ Azari but is not believed to be currently living there.
