Horncastle Police have warned that vandals attacking cars parked on one of the town’s busiest roads are putting lives at risk.
Police have confirmed vehicles parked on Lincoln Road have been targeted in recent weeks.
Many of the vehicles are owned by pupils at Queen Elizabeth’s Grammar School.
Police say engine, fuel supply and tyres have been tampered with - rendering vehicles unsafe.
They add that at least two pupils from the school reported problems controlling their cars after their tyres had been let down.
Police have responded to the complaints by visiting QEGS and talking to pupils.
Officers stress patrols are being stepped up in the area and say they will take “robust action” against any offenders.
PCSO Nigel Wass said: “This is not just someone having a laugh. It is criminal damage.
“By tampering with the cars and letting tyres down, they are genuinely putting people’s lives at risk.
“Their actions could lead to someone having a serious accident.
“The pupils are obviously concerned but we will do everything we can to catch whoever is responsible.”
PCSO Wass stressed the cars were not breaking any parking regulations and played down reports that the attacks were being carried out by people fed up of vehicles parking outside their homes.-
