Police in Germany have made a breakthrough in the probe into the disappearance of Hartlepool youngster Katrice Lee.
Katrice went missing on her second birthday on November 28, 1981 from a NAAFI shopping complex in Paderborn, Germany, where dad Richie, from Hartlepool, was serving as a Sergeant Major in the army.
Police in the country have now released an image of a suspect they would like to speak to in connection with Katrice's disappearance.
An eyewitness is said to have seen the man carrying a small child into a green saloon vehicle at the time of the disappearance.
The e-fit of the man was featured on last night's episode of BBC show Crimewatch.
WO1 Richard O'Leary, from Royal Military Police, told the programme: "We have a witness who has produced a photo-fit of a man seen holding a child similar to Katrice and getting into the back of a green car outside the
"We want to know who that person is and if anyone can come forward.
"We have had some information back, and need to check and verify those details, but we were really grateful to receive that information and we will check.
"The Katrice Lee family have had a 36-year nightmare, not knowing what has happened to their daughter or sister.
"If we can help solve what happened to Katrice and give them some sort of resolution, that would be really good.
"If someone does know what happened to Katrice we'd like them to come forward, or if they had a green car themselves and had a child similar-looking to Katrice, we'd like them to come forward so we can eliminate them.
"There were 1,500 people in the shop that day so someone will have seen what happened."
