Detectives are investigating after receiving reports that a woman was injected with an unknown substance while in a nightclub over the weekend.

Police were called at 4.45pm on Sunday after a woman in her late teens had attended hospital with concerns that she had been injected.

It is believed she had been out with friends in Switch nightclub in Preston, with police saying the window for the incident to have occurred being between 10.20pm on Saturday and 4.45am on Sunday.

Officers are also looking into a separate incident after they were called to Lancaster Road, also in Preston city centre at 11.57pm on Saturday by the ambulance service following reports two women had their drinks spiked.

The women, one aged in her 20s and the other in her 30s, were take to hospital but have both since been discharged.

Detectives are at the early stage of their enquiries and although the two incidents are not being treated as linked at this stage, officers are keeping an open mind.

Nobody has been arrested at this time.

Det Insp George Binns, of Preston CID, said: “We appreciate that there is a great deal of concern surrounding these reports, particularly on the back of what has been reported elsewhere in the country.
