Police have detained a Myanmar man and his mother believed to be involved in several cases of house burglaries around Ampang.

Ampang Jaya deputy police chief Supt Nazri Nawawi said the man and his mother aged between 20 and 40's were nabbed in a raid at a house in Lembah Maju, Ampang at 12.20pm on Monday.

He said in the raid, police seized goods valued at RM50,000 believed to be from house burglaries including 11 mobile phones, 13 watches, an Ipod, 20 necklaces and a bracelet as well as several pendrives and a broadband modem.

"Investigation found that the man, who is unemployed, has previous criminal records for snatch thefts and burglaries in Dang Wangi and Klang," he told reporters.

Nazri said initial urine screening on both suspects found the man to be positive for methamphetamine but the mother was negative for drugs.
