Phil Beer was with his friend Patrick Barnes in the bombed tube

Hair stylist Phil Beer, of Borehamwood, Herts, was with friend Patrick Barnes when the explosion struck between King's Cross and Russell Square.

The two spoke in the darkness of the bombed Tube train after the blast but Mr Beer has not been seen since.

Mr Beer's sister Stacy, 24, said: "It's the wait that's the worst. There is nothing we can do."

Ojara Ukeagwu's husband last saw her at Luton railway station

Mr Barnes, 22, who suffered burns and a broken leg, managed to crawl from the wreckage and make his way to the platform at Russell Square where he used his mobile phone to contact Stacy.

On Wednesday, she said she and her parents, Phil and Kim, were feeling "emotionally drained".

Also missing is married mother-of-three Ojara Ikeagwu, 55, from Luton, Bedfordshire.

Mrs Ikeagwu, a social worker, caught her usual train into King's Cross on her way to work in Hounslow and would have taken a Piccadilly line Tube to get there.
