Police Increase M11 Patrols
Extra police officers are now patrolling parts of the M11 motorway in Cambridgeshire, after a number of rocks were thrown off bridges at drivers.
Last Thursday, an object was thrown at a lorry travelling along the southbound carriageway close to junction 11.
The driver was not hurt, but their windscreen was smashed.
Then just after midnight yesterday, another object was thrown at a lorry on the northbound carriageway.
Again, the vehicle's windscreen was smashed but the driver was unhurt.
Shortly after that, another rock was thrown at a lorry in a similar location.
The 47 year old driver had to be taken to Addenbrooke's Hospital for treatment.
More police officers are now patrolling the motorway.
Detective Inspector Matt Potts said: "These are extremely dangerous acts that could result in someone being seriously injured of even killed.
I would like to hear from anyone who has information about these incidents."
Anyone with information is asked to contact DI Potts on 0345 456 456 4 or Crimestoppers, anonymously, on 0800 555 111.
