A cordon remains under police guard following an over night fire.
Hampshire Constabulary have launched a joint arson probe in the town of Bishop Waltham.
The investigation follows a serve fire that had ripped through a fast food kebab wagon leaving the owner gutted.
Fire crews were called late on Monday evening after the blaze took hold.
Due to the quick intervention and fire fighter crews managed to stop the blaze from following engulfing a second business Arch Associates building.
The rear of the building was partially damaged from heat and flames.
This is the second time within a matter of months that the van has been attacked and torched.
