XI'AN - A drug dealing network spreading across five provinces has been cracked, police in Northwest China's Shaanxi province said on Wednesday.

Shaanxi police said it arrested 34 suspects and 68 drug users, with more than 30 kilograms of drugs and nine vehicles being seized.

The network spread across Guangdong, Hunan, Anhui, Zhejiang and Shaanxi provinces.

The network's ringleaders were caught when they were transporting drugs from Guangdong to Shaanxi.

According to Shaanxi provincial public security department, police found clues pointing to the drug dealing network after arresting six drug users in March. Police set up special teams which spent several months investigating.
