A shotgun was fired during a violent robbery at a farmhouse in which firearms were stolen, detectives have said.
Police have renewed their appeal for information after the incident in Adlington, near Chorley, on Friday.
They have released images of guns similar to those stolen in a bid to try to trace them and to find the offenders.
A group of three or four men wearing balaclavas forced their way into a farmhouse off a private road off The Common, in Adlington, at around 9.40pm.
A 50-year-old man was tied up and threatened with a shotgun and machete, while the men demanded money and access to the owner’s firearms.
A shotgun was discharged during the incident, although no-one was hurt.
“The level of violence shown during this robbery was frankly shocking and it is only by chance that no-one was seriously hurt.”Det Insp Jo Keay
Seven firearms were taken from a gun cabinet along with ammunition and around £5,000 in cash.
The men left in the owner’s maroon Land Rover Discovery which was later found abandoned on Thirlmere Road in Blackrod.
Det Insp Jo Keay, who is leading the investigation, said: “The level of violence shown during this robbery was frankly shocking and it is only by chance that no-one was seriously hurt.
“We believe that this was a targeted robbery and that the offenders knew that there were guns in the house.
“Thankfully incidents like this are rare and I would like to reassure the public that we have a dedicated team of officers working on this investigation.
“We are determined to find the men responsible and the firearms that they took but we need the public’s help to do that so I would urge anyone with any information to contact us.”
Anyone with information is asked to call Lancashire Police on 101, quoting incident reference 1363 of November 13.
