Three men have been arrested by detectives hunting the killers of a young City lawyer stabbed to death just before he reached his front door in Kensal Green.

Last Thursday night the vicious knife attack on Tom ap Rhys Pryce, 31, continued even after the two robbers had taken his belongings.

Yesterday at around 5pm officers arrested three men in the street in nearby Kilburn. They are now being questioned at various London police stations.

Mr ap Rhys Pryce was attacked as he walked up Bathurst Gardens, north-west London, towards the house he shared with his fiance, Adele Eastman.

Just over an hour earlier he called her from a party to say he would be home by 11.30pm. But shortly after midnight he had died in hospital.

The couple planned to marry in September, a year after they had met.

The Cambridge graduate was captured on CCTV minutes before his murder as he left Kensal Green station at 11.25pm.

Police believe he followed unknowingly in the tracks of his two suspected attackers, who were filmed on the station platform as they robbed a second victim, an Asian man, at 11.10pm.

The next morning CCTV cameras recorded a man as he tried in vain to use what was thought to be the Linklaters solicitor's Oyster card to enter the station.
