A woman had her drink spiked at a pub in Northampton town centre, police have reported.
A spokesman for Northamptonshire Police said they were appealing for witnesses after the incident in the Wig and Pen in St Giles Street.
“The woman was in the Wig and Pen on Saturday November 12 and sometime during the evening it is believed a noxious substance was added to her drink without her knowledge. She began to feel unwell and called a friend who came to pick her up.
“The incident happened sometime between 10pm on Saturday and 12.30am on Sunday.
“At some point during the evening, a man joined the woman at her table. He is described as Asian, about 40 years old, with mid-length dark hair which was swept back, and officers believe he may have information about the alleged incident,” he said.
Anyone with information is asked to contact Northamptonshire Police on 101. Alternatively, they can call the independent charity Crimestoppers anonymously on 0800 555 111.
