Firefighters rescued two women trapped inside a first floor flat in St Helier last night, after a large fire involving eight motorcycles and the side of a building started.
Two fire engines and nine fire fighters were called out at 3am to tackle the blaze.
Jersey Fire & Rescue say the heat generated was so intense that it cracked the windows of properties on the other side of the street.
Firefighters entered the flat through a window to give the women medical care while the fire was tackled.
The fire service had to clear smoke from inside and the two women were treated by paramedics and taken to hospital.
They have since been discharged.
The cause of the fire is unknown but it is being treated as suspicious.
Police are appealing for anyone who may have seen anyone in the area early this morning or has any information in relation to this incident to come forward. They also want to speak to anyone who parks their moped or motorcycle in this parking bay. Call 01534 612612.
