Four people were arrested after police raided a house in Upper Union Street, Aldershot, on April 2 as part of a crackdown on drug-related violence.

Nine plain-clothed and uniformed officers stormed the property at around 1.25pm, taking into custody a 35-year-old man and a 24-year-old woman, both from Aldershot, and another man and a woman, both 43 and from Tiverton in Devon.

They were arrested on suspicion of possessing a Class A drug and were led to a police van in handcuffs.

Officers could also be seen removing a number of plastic bags from the house.

The warrant was executed as part of Hampshire Police's Operation Fortress, which aims to reduce the harm of drug-related violence by restricting the supply of Class A drugs.

PC Charlotte Dugdale, in charge of the operation, said people should be on the look out for a sudden increase in visitors to a house or flat, and for people staying for a very short time.

She also said short exchanges between small groups of people close to a property, and people loitering in an area and using their mobile phones frequently might also indicate drug-related activity.

PC Dugdale also warned people to be aware of new-looking or hire cars parked outside a house or flat that wouldn't normally be there.

Anyone with concerns should contact police on 101 or call Crimestoppers charity anonymously on 0800 555 111.
