Marsha police in new plea

Scotland Yard are desperate to speak to two men about the moments leading up to the brutal killing of student Marsha McDonnell.

Police have so far been contacted by eight of the 10 people filmed in the same area as Marsha shortly before the attack.

Despite an "excellent" response from the public after police retraced the 19-year-old's last steps on Monday night, there are no new leads in the hunt for the killer, who struck when Marsha was yards from her home in Hampton on Tuesday last week.

Without a murder weapon, or any description of the attacker, detectives are continuing to appeal for witnesses.

After a high-profile appeal to three men who shared Marsha's bus home from Kingston - route 111 - only one has come forward. The other two boarded the bus together outside John Lewis.

Both were described as Asian. One was short, in his twenties with short dark hair, and wearing an opennecked anorak. He sat upstairs at the back with the other man, who wore a black peaked cap and black leather jacket.

Police emphasised neither is being treated as a suspect.
