Beijing police have warned people they may face arrest for wearing Halloween fancy dress on the subway due to safety concerns, The Beijing News reported.

With Halloween's arrival, the wearing of fancy dress or scary makeup on the city's extensive subway network could cause panic or disrupt order in the public transportation system, Beijing police stated on its official Weibo account.

Subway staff will stop passengers who are wearing strange customs or "frightening" makeup. Resistors may face arrest, say police.

"If they cause any public security incidents, such as stampedes, the police will deal with it severely," The Beijing News noted.

Halloween became popular in Chinese big cities though with no religious connotations. In the past two year, passengers wearing strange clothes often gathered in subway stations near Sanlitun in Chaoyang district, where many Halloween parties have been held, Beijing police pointed out.

Some "horrific" Halloween outfits and makeup of passengers have caused panic in the subway stations in cities, such as Shanghai and Wuhan. Subway enterprises normally cannot deal with such issue as these are personal behaviors rather than legal violations, according to previous media reports.

"I've seen two passengers, probably foreigners, in strange outfits being stopped by staff at the entrance of Fuchengmen Station on Line 2. It is a good practice as not everyone can accept such events," a 32-year-old passenger, surnamed Liu, told the Global Times. 

The Beijing police also warned that people need to be cautious of theft as many people wore similar masks in Halloween parties and people might misidentify their friends.

The Reuters stated that warnings to Halloween outfits are part of the boosted security measures in the run-up to the Asia-Pacific Economic Cooperation meeting in early November.
