Crews were called to two blazing vehicles, approximately 10m apart in a Brindleyford car park at 00:55am.
Shortly after, crews received a second call at 00:57, where a further three vehicles were reported on Brackenfield Road. No people were involved in either incident.
Head of operations and risk management Simon Hardiman said: “This was a particularly dangerous scene due to explosive fuels, proximity of the vehicles to residents and the multiple locations. One of the vehicles had also travelled 300m due to fire damage and came to a stop in the rear garden of a property.
“Fuel leakages meant that the fire area around the vehicles was extensive and each car was at a different stage of damage.
“As this was in the early hours of the morning, thankfully nobody was physically injured however the impact on residents has been very distressing.
“I’d like to commend our crews for their response times and for bringing the scene under control in an effective way.
“These types of incidents take up valuable resources and ultimately put the public and firefighters at risk, not to mention the disruption to infrastructure and property. The fires are believed to have been started deliberately and investigations are ongoing.”
A total of six fire appliances were mobilised from Much Wenlock, Telford Central and Wellington stations along with crews and a fire investigation officer. The Police were also in attendance.
Anyone with any information is asked to make contact with West Mercia Police on 101 or Crimestoppers anonymously on 0800 555 111.
