'Vulnerable' Speight in CCTV images

His family said he was in a "vulnerable" state following the death of his fiancee, Natasha Collins.

Speight, 42, was captured on camera entering Queen's Park Tube station in north-west London at 2.25pm on Monday afternoon. He was last seen 22 minutes later boarding a southbound Bakerloo Line train heading towards the centre of the capital.

The presenter was reported missing after failing to keep an appointment to meet his dead fiancee's mother, Carmen Collins, 57, for coffee in Covent Garden at 3.30pm the same day.

Speight's disappearance came just six days after the inquest into 31-year-old Miss Collins's death, which he attended looking drawn and gaunt.

On January 3 he found the body of his fiancee, also a TV presenter, covered in extensive hot water burns in the bath of the penthouse flat they shared in north-west London.

Speight told police the couple had been "partying" and had taken cocaine and sleeping pills as well as drinking wine and vodka. He was initially arrested on suspicion of murder and supplying Class A drugs, but last month Scotland Yard said he would not face any charges over the death.

Detectives have now released fresh details of his last known movements.

Speight was dropped off at Wood Green station in north London at 9.30am on Monday and was later seen walking along Chamberlayne Road between 1.15pm and 1.30pm.

At 2.18pm he withdrew money from a cash machine just 20 metres from Queen's Park station before boarding the Bakerloo line train at 2.47pm.
