Heroin seized by city RCMP during a search of a suspected trafficker's motel room was enough to keep Kamloops supplied with the illegal drug for months, a judge was told Friday.

Guljit Singh, 43, was in provincial court seeking his release from jail. He was arrested Wednesday after drug officers were tipped by an informant about the presence of heroin at an Aberdeen motel.

Federal Crown prosecutor Anthony Varesi opposed bail for Singh, noting the evidence suggests the man was involved in trafficking significant amounts of heroin, a drug Canada's courts consider to be one of the most addictive, socially destructive and dangerous to be found on the streets.

Varesi said this bust is the largest in recent memory in Kamloops. The 502 grams of heroin seized, equal to about 5,000 individual hits, has a street value of about $100,000, the judge heard.

The Crown lawyer said police surreptitiously watched Singh for hours before his arrest. They watched as he met a man near a Kamloops convenience store. That 10-second meeting looked like a drug transaction, prompting the arrest of both of them.

Police found small quantities of heroin in the pockets of both men, the court was told, while Singh also had cash and a cellphone with text messages suggestive of drug dealing.

Officers later obtained a search warrant for Singh's motel room. The inn's manager confirmed he and his wife had been living there for about two weeks.

Defence lawyer Jeremy Jensen said his client does not need to be detained, as he can live with other family members in Kamloops under strict court conditions.

Jensen told the judge Singh, who is married and has two children, is enrolled in university courses at Thompson Rivers University.

Judge Sheri Donegan said she needed to review the law and the facts of this case, and adjourned her decision until Monday.

Singh will remain in custody until then.
