Drug dealers operating out of an upmarket flat in Bayswater were caught on camera by their own internal CCTV system, a court heard.
Police found the footage of them putting drugs into bags and counting money when they raided the flat in Kensington Gardens Square, Southwark crown court was told.
Veerapatra Piriyachotworakul, 50, who owns the flat, and Aaron Milton, 70, have pleaded guilty to conspiracy to supply drugs including crystal meth.
A third man, Liam Pilgrim, 33, was also said to have been seen on the CCTV footage but denies being involved in supplying drugs.
Det Con Dylan Enright told jurors yesterday that the flat was rigged with four CCTV cameras covering every room plus a monitor to show people approaching the front door.
Pilgrim, from Westbourne Grove, is now in the dock alone after the other men’s guilty pleas, and the trial continues.
