TORQUAY firefighters were called out three times in less than an hour on Friday morning to deliberate fires in the same small area of the town.
They are the latest in a spate of arson attacks to hit the town in recent months.
DC Nikki Zulhayir told BBC News: "They will all be treated in the same manner.
"The investigation is ongoing."

The first call came at 2.55am to Braddons Hill Road West in the town centre, where two crews dealt with a shed on fire after receiving a number of calls from members of the public.
A fire service spokesman said the fire had been started deliberately and had caused severe damage to the shed.
The spokesman said that investigations were carried out due to a number of deliberate fires in this area and police were also making inquiries.
A quarter of an hour later, while the original crews were still dealing with the shed fire in the town centre, a further fire appliance from Torquay was sent to nearby Ellacombe Church Road after more calls from the public saying a vehicle was on fire.
The car was well alight and again a service spokesman said the blaze had been started deliberately.
Half an hour later, at 3.40pm, more calls came in of a building on fire in Windsor Road, Ellacombe.
The original Torquay crews had just finished dealing with the Braddons Hill shed fire, and one was sent along with colleagues from Paignton.
The fire in the semi-detached store building, around four metres by eight metres, was put out by firefighters using four sets of breathing apparatus, two hosereel jets, one covering jet and a thermal image camera.
The matter was agsin left in the hands of the police.
The fire service spokesman said: "This was again confirmed as deliberate ignition and therefore possibly linked to the two previous other fires."
