PHUKET: Police on Phuket are investigating a fire that damaged three vehicles at a landscaping business early today.

Forensic police investigators are expected to confirm that the blaze was deliberately lit soon after 1am.

It's believed fuel and tyres were used to ignite the fire at Phuket Landscaping International, which is based in a shophouse on the road between the Heroines' Monument and Cherng Talay.

A spokesperson at the landscaping firm said today: ''We can't say anything yet.'' An Australian has a connection to the firm, the spokesperson confirmed.

A full assessment of the damage has yet to be made.
