Six firework pranks on Northamptonshire homes could have resulted in deaths, arson experts have said.
In the past three weeks there have been six incidents involving fireworks in Northamptonshire reported to police, two in Northampton, one in Towcester, two in Wellingborough and one in Corby.
Police said the most serious took place this week, when fireworks were put through letterboxes in Caernarvon Close, Towcester, Compton Road, Wellingborough and Wareham Green, Corby, causing fire damage to the properties and endangering lives.
They follow similar incidents in other parts of the UK, which resulted in rescues from house fires.
Mick Rodden, a fire officer from the Northamptonshire Arson Task Force, said: “We are shocked and dismayed by these thoughtless acts. What is thought to be a bit of fun can lead to the deaths of whole families.
“When any fire is started it has the potential for rapid uncontrolled spread which can engulf a house and entrap the occupants in a few minutes.”
Shaun Johnson from Arson Task Force (Police) added: “These are reckless acts which can carry a life sentence on conviction.”
Investigations are continuing into the fires.
Anyone with information about any of these incidents can contact Northamptonshire Police on 101 or Crimestoppers 0800 555 111.
