The British police have arrested one more man in connection with the murder and disappearance of NRI millionaire Amarjit Chohan and his family.

Scotland Yard told PTI on Tuesday night that a 54-year-old man was being questioned about the disappearance of Chohan and his family from Heston, west London in February.

The body of 46-year-old Chohan, who had a flourishing 4 million pounds transport business, was discovered washed up near Bournemouth pier in Dorset on April 22.

His 25-year-old wife Nancy was also found in the sea off Dorset on July 15.    

Their two young sons, Devinder and Ravinder, and Mrs Chohan's 51-year-old mother, Charanjit Kaur, are still missing.

Peter Rees, 38, of Rowlands Castle, Hampshire, has been charged with the murder of all five family members.

He has also been charged with preventing Chohan's burial.

Chohan and his family vanished from their home around February 16. A police investigation began after the alarm was raised by Nancy's New Zealand-based brother.

In August, Kenneth Regan, 54, from Salisbury, Wiltshire, was detained in Belgium awaiting extradition.
