TWO students jumped from a first floor window in their Southampton home after thinking their house was on fire last night.

In fact, a smoke bomb had been thrown through the letter box of their home in John Street at about 9.30pm.

Thinking the house was on fire as it filled up with smoke, the two occupants jumped from the window at the front of the house to escape.

A fire crew from St Mary's fire station were called and cleared the smoke from the house.

A police investigation is now underway to catch the culprit.

If you have information, call 101.
