Gerald Matovu, 23, of Great Guildford Street in Southwark today pleaded guilty to supplying Barking serial killer Stephen Port with Class B drug mephedrone and Class C drug GHB between July 1 and August 31 2015.

He also admitted offering to supply GHB to Port between the same dates after messages on from the killer’s electronic devices revealed messages from Matovu saying he had “loads of G[HB]” and asking how much he wanted.

Matovu will be sentenced on April 26.

Port, 42, who lived in Cooke Street, Barking, was sentenced to life on November 25 after murdering four young gay men with GHB – including 25-year-old Dagenham forklift truck driver Jack Taylor – from June 2014 to September 2015.

Communication records obtained by the police indicate Port bought the drugs from Matovu for use during consensual sex with his partner.

Records also revealed Port had told his partner Matovu was his drug dealer.

Investigating officer Det Const Bhulesh Pala said: “Matovu’s activities became apparent during the investigation into Stephen Port and I am pleased we have been able to convict him today.”

Port was also found guilty of four rapes,

four sexual assaults and 10 counts of administering a substance with intent.
