A 19-YEAR-OLD arrested as he allegedly tried to offload 1000 ecstasy pills while undercover police watched will not have to ring his mother to bail him out of jail - she drove him to the meeting.

Undercover city detectives arrested the teenager as he allegedly tried to sell the pills in a car park in Ramsgate Avenue, North Bondi, about 10.30am yesterday.

There was no evidence the mother was involved in any criminal enterprise or was aware of her son's illicit activities, police said.

Police also questioned three men in a nearby car.

The teenager was taken to Bondi police station and charged with supplying a commercial quantity of a prohibited drug.

Later, police also arrested a man, 26, at a house in Westmoreland Street, Glebe, whom they allege was the source of the drugs.

The commander of the Surry Hills Region Enforcement Squad, Inspector Gavin Wood, said yesterday's arrest was one of five his squad had made since May.

About 2200 ecstasy tablets with a street value of about $110,000 had been seized during Strike Force Dooley, which targeted mid-level drug distribution in the city and surrounding suburbs, he said.

Since May the squad has arrested 104 people for 200 drug-related offences.

"We'd certainly allege that [yesterday's operation] is a very significant seizure and we believe we've hit a significant drug distribution network. We are constantly targeting those people engaged in dealing illicit drugs and taking them off the streets.

"Every drug arrest we make further disrupts the supply network and … we will only continue to step up our activities."

The 19-year-old was expected to appear in Waverley Local Court yesterday. The 26-year-old has been charged with supplying a commercial quantity of a prohibited drug and will face Newtown Local Court at a later date.
