District Deputy Police Chief Supt. Keong Ho Eng said the first suspect, aged 22, was detained at a shop lot along Mile 8, Jalan Apas about 1.50am on June 6, while the second, aged 29, was picked up at the Flat Sri Apas, Mile 8, about 1.30am on June 10.
"The third person, aged 23, was arrested in front of a restaurant along Jalan Persisiran about 2.30pm on June 10, while the fourth person, a 33-year-old foreigner, was nabbed at the Sabindo area about 3pm on Wednesday," he said.
He said the foreigner is the person who supplied and forged the road tax and registration documents of the Vigo, adding that police also seized the vehicle which was sold for RM15,000, adding that inspections on the vehicle showed it was indeed the vehicle reported stolen.
Keong said the vehicle was reported stolen by a 44-year-old woman who claimed that she was robbed by two men armed with machetes near a dental clinic along Jalan Dunlop about 11pm on June 4.
"One of them held the machete to her neck, while the other pointed his machete to her abdomen before making off with her handbag, two handphones and a set of car keys.
"They then fled in the Vigo which belonged to the woman's husband," he said, adding that the woman had parked the vehicle some 30 metres away from her house.
The case, he said, is being investigated under Section 395/397 of the Penal Code.
He said police are now on the lookout for two people, believed to be the main suspects, without revealing their identity.
He said detailed investigations are being done to determine whether the case involved a syndicate forging documents and also if they are involved in other cases as the number of vehicle thefts in the district has shown an increase.
