Officers from Hampshire Constabulary are now linking 13 arsons that have occurred between August 3 and August 24 that have occurred mainly in the early hours of the morning between midnight and 5am.
Only a few of the incidents have caused minor damage. The rest have caused a significant loss of property.
Officers have been conducting enquiries in the local areas affected by these incidents and have encouraged residents to report anyone acting suspiciously to 999.
Detective Inspector Adam Edwards from the Western Investigation Team said: “We have seen several vehicles, caravans and motorhomes been completely burnt out as a result of these fires. More recently, the fire has spread to a house and endangered people’s lives.
“We would urge anyone who owns a caravan or a motorhome not sleep to in it whilst parked outside your house or on your driveway. Make sure it is secure and locked and remove any gas canisters and any other potentially flammable household items and materials.
“We have images of a person we would like to trace captured from the cameras on the fire engines that have been called to the scene. This person has been in the area at the times the fires have been reported and watched the emergency services.
“Police would like to speak to anybody who recognises the person in these images. We know they are grainy pictures, but someone might know this person. If you do, please get in contact.”
