Cape Town - A suspected drug courier had a less than peaceful Sunday afternoon when a drug delivery in Bellville was intercepted.This was the second narcotics-related arrest on the weekend when a tip-off from the public led to suspected drug dealers being arrested.Cape Town’s law enforcement agencies arrested 86 suspects during weekend operations – 68 of them for drunk driving, seven for drug-related offences, and several others for possession of stolen property and riotous behaviour, the city said in a statement on Monday.The Metro Police Gang and Drug Task team, acting on a tip-off, arrested a suspected drug courier when they intercepted a delivery in Bellville."When they pulled him over, officers identified the driver of the Fiat Palio as a suspect who was arrested in July for possession of drugs. Officers found a packet of tik, five packets of dagga, and just over R1 310 in cash in the man’s possession," the statement said.On Saturday, another tip-off led the Tactical Response Unit to a house in Beacon Valley, where officers found dagga in the house as well as several packets hidden in a barrier wall in the yard.They arrested a 19-year-old suspect and also confiscated R14 869 in cash."These are both good arrests and came from credible information from the public," said mayoral committee member for safety and security JP Smith."We are thankful to residents who have had enough of these drug peddlers in their communities and who are standing up by blowing the whistle.Harder line needed"It is a little disheartening, though, that our staff continues to come across familiar faces. No doubt the communities who see drug dealers arrested today and back on the street tomorrow feel the same. So I would appeal to the criminal justice system to take a harder line on these offences." Metro Police arrested 19 motorists for drunk driving – 11 of them along the Voortrekker Road corridor in Goodwood, Parow and Bellville.Cape Town Traffic Services arrested a motorcyclist and his passenger in Belhar after they sped off against the flow of traffic in an effort to dodge a road block.Officers later found the motorcycle had been reported stolen in Ravensmead.The passenger was found with a rucksack full of suspected stolen goods, while the driver had a tik 'lollie' in his possession.
