A multi-millionaire property developer's son is being questioned over the disappearance of a blonde waitress from a celebrity club popular with Premiership footballers and soap stars.

Privately-educated Westley Capper, 37, has already admitted driving Agnese Klavina, 30, away from the nightspot in the upmarket Costa del Sol resort of Puerto Banus.

Police believe 5ft 7in Agnese was forced into the vehicle. 

And the overweight expat - who has never been publicly named - showed he was in little mood for co-operating by refusing to be questioned after being summonsed to court yesterday.

The Spanish judge investigating Agnese's disappearance from trendy Aqwa Mist, where footballer Ashley Cole, Hollywood star Eva Longoria and boxer Amir Khan have all partied, was last night expected to order a fresh round of DNA tests after his hopes of an early breakthrough in the case foundered.

Capper, whose Essex-born dad John specialises in buying and selling luxury properties around the world, has had travel restrictions imposed on him while the investigation against him continues.

Co-accused Craig Porter, 33, also declined to answer questions during a closed court hearing in Marbella.

The two men left the hearing in an English-plated Range Rover they had left parked in a disabled bay near the court.

Agnese, whose British boyfriend, Michael Millis, is a former owner of west London club Westbourne Studios, vanished on September 6 last year after leaving Aqwa Mist with the two Brits.
