Three greedy businessmen executed an NRI family of five in a crime which was "beyond belief", the prosecution has told a London court.

The NRI businessman Amarjit Chohan, his mother-in-law, wife and two children were victims of a plot to hijack a firm and turn it into a front for drug smuggling, prosecutor Richard Horwell told the Old Bailey court on Monday.

Chohan was lured into a trap at Stonehenge and held prisoner before being killed. His family members were then murdered to make it look as if Chohan had sold his business and gone abroad, he told the court.

Their bodies were buried in Devon, then dumped at sea. The key figure in the plot, 55-year-old Kenneth Regan had
allegedly met Chohan at Stonehenge in February last year.

The meeting was arranged by Regan's accomplices Wihliam Horncy and Peter Rees, the prosecutor said, adding after leaving his office in Southall, Chohan was never seen again.

Four days later, Regan came to the office of Chohan's CIBA freight company brandishing a power of attorney enabling
him to run it.

Between those two dates, Chohan's wife Nancy, their two children, Devinder and Ravinder, and her widowed mother Charanjit Kaur "were sucked into the wickedness," the court was told.

Regan from Salisbury, Wiltshire, Horncy from Bournemouth, and Rees from Rowlands Castle, Hampshire, have pleaded not guilty to five charges of murder and a count of false imprisonment.
