INCHEON, Police said Wednesday they have seized 10 disposable hypodermic syringes and some cotton balls at the house of a grandson of late Hyundai Group founder Chung Ju-yung.

The Incheon Metropolitan Police Agency served the 28-year-old, who is the eldest son of Chung Mong-il, the eighth son of the Hyundai founder and CEO of Hyundai M Partners Co., with an arrest warrant on Monday after detaining him the previous day upon his arrival at Incheon airport, west of Seoul.

Nine of the 10 were not used and the remaining one appeared to have been used, the police said.

The younger Chung is suspected of illegally using liquid marijuana in cartridges on 11 occasions at his home in Seoul from March last year to January after making seven purchases of the outlawed substance from a 27-year-old drug dealer, only identified by his surname Lee.

During interrogations, Chung was quoted as saying he used a syringe once to transfer a liquid form of marijuana coming from a broken cartridge and he never administered other drugs, including methamphetamine. He also told investigators that he used cotton balls soaked in alcohol to treat unspecified skin troubles.

The police raided Chung's house prior to his returning home and sent one of the syringes to the National Forensic Service to confirm the credibility of Chung's testimony.

Chung is also suspected of having smoked marijuana with another chaebol family member, the arrested 31-year-old grandson of the late founder of SK Group, once.

Chung left for Britain one week before the drug seller, Lee, was arrested in February for suspected drug use.

Investigating authorities have confirmed circumstances that Lee sold the substance to Chung, who met Lee while studying abroad.

Meanwhile, the police have taken custody of two alleged drug peddlers one is 33 years old and the other 32 years old who allegedly supplied liquid marijuana in cartridges to Lee.

Chung, who has been staying abroad since February, had said via his lawyer that he intended to return home soon to undergo police questioning over the allegations.
