Alex Jeffery, of Orchard Road, died at Addenbrooke’s Hospital on Saturday, a week after he was hit by a car at about 3.30am on November 1, outside the Cambridge City Hotel on Downing Street.

He had been involved in an altercation in the street prior to the incident.

A post mortem examination will take place later this week.

His family have released the following statement: “Alex was a fun-loving, kind and caring son, grandson and brother. He is so missed by us all.”

A 24-year-old man from Huntington has been arrested on suspicion of murder in connection with the death of Mr Jeffery and remains in custody at Parkside Police Station in Cambridge.

Det Insp Jerome Kent, of the Bedfordshire, Cambridgeshire and Hertfordshire major crime unit, is leading the enquiry.

He said: “I believe there are still people out there who witnessed this incident but still haven’t been in touch with the police, and I would urge those people to pick up the phone and call in.

“In particular I am keen to speak to the two security guards who came to Alex’s aid.

“I would also urge anyone who may have been travelling in the car involved in this incident or knows who the driver is to come forward.

“We are viewing CCTV from the area so it is only a matter of time before they are identified.

“This is a devastating and traumatic time for the family and is it vital we catch the person responsible.”

Anyone with information should contact the major crime unit on 101 or Crimestoppers, anonymously, on 0800 555 111.
