FOUR men have been arrested in connection with the murder of art student Natalie Janiak.

The men, aged 18, 19, 21 and 23, were arrested in Blackheath at 2am this morning (Feb 21) by Kent Police.

They are being held at police stations in Chatham and Gravesend.

Earlier this week, police released without charge two men they had been holding over the weekend. One, a 19-year-old, however was bailed on vehicle offences.

Natalie, 18, of Humber Road, Westcombe Park, south east London, was found in an alley in Wilmington near Dartford last Saturday (16) morning. A post mortem revealed she died of asphyxiation.
