A DARWEN woman has been treated for a wrist injury after a group of 30 men descended on her house.

Police said the incident, which occurred at 10pm on Monday in London Terrace, followed an altercation at a nearby shop between the woman’s son and the shop owner.

A 24-year-old man, believed to be a resident of the house, had been cautioned for making racist and abusive comments.

The shop owner is believed to have mobilised a group of up to 30 family and friends to track the son down to his home in London Terrace.

The group of Asian men also smashed a car window in the street before dispersing when police arrived at the scene.

Last night, none of the group had been traced and police were making house-to-house inquiries.

A spokeswoman for Lancashire Constabulary said: “This was not a random incident.

"An investigation is ongoing.”
