DNA evidence has given detectives hope of solving the case
Detectives trying to solve the murder of a teenager from Bath 25 years ago say they are pleased with the response to a TV appeal.
Melanie Road, 17, was sexually assaulted and stabbed to death as she made her way home from a city nightclub in the early hours of 9 June 1984.
A reconstruction of the events leading to the attack was shown on BBC One's Crimewatch programme.
Police appealed for new information and took more than 40 calls.
During the show officers asked viewers to cast their minds back to 1984 and see if they could remember anyone who appeared with unexplained injuries or left the city suddenly.
Officers believe they have the killer's DNA from the crime scene. The profile does not match anybody on the national database.
Det Ch Insp Mike Carter said: "If there was someone acting suspiciously, at that time, we can check them against our DNA sample."
