Hong Kong woke up to a deadly arson attack on Thursday, with 37 parked motorcycles going up in flames at a tourist destination. 

The motorcycles parked under a footbridge caught fire at the popular Wong Tai Sin area at about 3 am on Thursday, South China Morning Post reported. 

Authorities called the incident an arson attack as no fire accelerant was found at the spot and the police described the fire as 'unnatural'. 

"One witness saw a motorcycle in the middle of a row of motorbikes first caught fire and then spread to the others," a police official told the newspaper. 

No injuries were reported in the incident, but the arson attack left the bikes charred and damaged nearby lampposts. 

The Fire Services Department of Hong Kong described the fire as 'suspicious', the paper reported. 

The incident comes days after fire broke out in an apartment in the area and a youth was found dead on the roof of the building on Monday. 

The area is named after Hong Kong's famous Wong Tai Sin Temple.
