ULAN BATOR, May 7 (Xinhua) -- Mongolian customs officers seized a parcel from Spain containing 3 kilograms of hashish, a type of narcotics, the Mongolian Customs General Administration (MCGA) said Tuesday.

The officers at the Chinggis Khaan International Airport in the capital of Ulan Bator seized the contraband, which is an extract of the cannabis plant containing concentrations of psychoactive resins.

The case is under further investigation, the MCGA said in a statement.

Drug-related crimes has been increasing significantly in Mongolia in recent years.

The Mongolian police have arrested 88 people linked to 29 drug-related crimes in the first two months of 2019, and arrested 412 people linked to 199 drug-related crimes in 2018, according to the National Police Agency (NPA).

A total of 72 drug-related criminal cases linked to 150 people, including 7 foreigners have been registered across the country so far this year, the NPA said in a statement.

A lack of knowledge about narcotics, curiosity, attempting to make easy money and weak law are the main factors for the growth of drug-related crimes, the NPA said.

According to Mongolian law, the person who is found guilty of trafficking drugs will be punished by imprisonment of at least two years.
