deliveries by a second black male. He stated that the heroin delivery was going to take place sometime after 8:00 p.m.
As indicated above, Sergeant Little relayed this information to Agent Frank Horn, a narcotics detective with the Jefferson Parish Sheriff's Office, who in turn gave the information to his partner, Agent Salvador Castagnetta. Agent Castagnetta discussed the information with Sergeant Little and set up surveillance of the residence. Upon his arrival at the residence at approximately 8:15 p.m., Agent Castagnetta observed a white van parked at the residence and a handicap emblem on the garage. Approximately five minutes later, Agent Castagnetta observed a black male exit the residence and leave in a blue vehicle.
*706 After the vehicle was stopped, a two-way radio was found on the front passengerseat in the "on" position. The investigating officer, Detective Ballard, was concerned that the driver, Shief, had advised someone he was being stopped by the police. The police also learned from Shief that he had picked up the heroin from 3712 Delaney Street. Shief further confirmed that a handicapped black male lived in the residence.
Clearly, the police had probable cause to arrest defendant and to believe contraband was located inside the residence at 3712 Delaney Street. There was information from a confidential informant regarding a delivery of heroin that was to originate from the residence. The informant named defendant as the heroin distributor. Sergeant Little testified that the confidential informant had provided reliable information in the past that had led to the recovery of narcotics and an arrest.
