Police are appealing to the public for information following a serious assault last month. 

Detectives investigating the incident are looking to trace a taxi driver who dropped off four people in the Paisley area in the early hours of Sunday, January 13, 2019.

The cabbie is said to have picked up two men and two women in the area of Bath Street and Hope Street in Glasgow City Centre in a dark coloured Skoda Octavia taxi.

He then took them to Paisley and dropped the group off at an address in High Calside shortly after 3.00am.

The vehicle had a light bar attached to the roof.

The two men who were picked up are described as being black, aged in their early 20s, and they spoke with North East English accents. Both women are white and aged 18 years.

Detective Constable Grant Spy, of Renfrewshire and Inverclyde CID, said: "I am keen to trace the man driving the taxi as he may have information which can assist our ongoing enquiry.

"I would like to emphasise that this individual is not considered to be a suspect and is being sought as a witness only. Anyone with any knowledge of his identity should get in touch with me as soon as possible via 101.

"I am aware that one of the men sat in the front passenger seat of the taxi and the other man sat in the rear, directly behind the driver.

"The route from Glasgow to Paisley would have been via the M8, exiting at Arkleston. He would have driven into Paisley town centre via Renfrew Road, Mill Street, Gordon Street, Causeyside Street, Calside and then into High Calside.
