POLICE have launched a hunt for two people who ran off after being involved in a high-speed car crash in Southampton.

Their car flipped on to its roof after hitting the central reservation of Millbrook Road at high speed at 3.20am on Saturday.

Witnesses say the pair then climbed free from the vehicle before running off.

Officers used police tracker dogs to try to trace the pair but were unsuccessful.

A spokesman for Hampshire police said: "At this stage no one has been arrested and no injured parties have been located.

"Our enquiries into the incident are ongoing."
