Hangzhou authorities have released more details in the case of a nanny accused of setting fire to an apartment in Hangzhou, Zhejiang Province, China News Service reported on Monday.

At a news conference, the authorities said the nanny had used her mobile phone to learn how to set a fire. They also said the property management company failed to maintain safe facilities and to provide emergency response.

The police said Mo Huanjing, 34, confessed after her arrest, and was charged on July 1 with arson and theft in connection with the blaze that swept through an apartment in a residential building on June 22. The fire killed a mother and her three children, aged 6 to 11 years, Li Bing, deputy director of the Shangcheng district public security bureau, said at the news conference.

Mo was addicted to online gambling, Li said. She had worked as a babysitter since 2015 in Shaoxing, Zhejiang Province, and in Shanghai, but was fired three times after being accused of theft.

She had worked for the family caught in the fire since September and had stolen items she subsequently pawned for 130,000 yuan (US$19,000) to pay off gambling debts. Mo also borrowed 114,000 yuan from her employer, claiming she needed to buy a house for her parents. During the investigation, the police discovered that Mo had searched such key words as “lighter”, “sofa fire” and “curtain fire” from 2 a.m. to 4 a.m. on the day of the blaze, the news service reported.

Later, at 4:55 a.m., Mo used a lighter to set fire to a book on a tea table. The fire spread to the sofa, got out of control and frightened Mo, who fled, leaving the mother and three children to die.

Firefighters arrived at the scene at 5:11 a.m., but the fire engine was blocked. Firemen rescued seven people but failed to reach the blazing room. Insufficient fire hydrant pressure prevented fire suppression and delayed the rescue effort, the report said.

According to Chen, the property management company had many problems with its emergency preparedness, including staff members who didn’t know how to switch on a fire hydrant pump manually.

A Juneyao Airlines flight from Beijing to Shanghai was delayed five hours after a child was found in the aircraft without a ticket, the airline said yesterday.

Crew on Flight HO1252, which was scheduled to take off at 6:55 a.m. on Sunday, found the child on board without a ticket.

The child passed the security check, the boarding gate and a final check before boarding the plane with the help of his family. He was accompanied by two adults and another two children, according to the Beijing Capital International Airport.

The five were asked to get off the aircraft, while all other passengers on the flight were asked to go through the security check again.

The flight eventually took off around noon after being delayed for nearly five hours. The child’s age and gender were not given.

According to civil aviation regulations, the security check authority should inspect the certificates of passengers along with other safety checks. If the authority failed to perform the duty, the civil aviation authority can face fines up to 30,000 yuan (US$4,433).

The airline has reported the incident to the Civil Aviation Administration of China, which has launched an investigation and will publicize the outcome, the airline told Shanghai Daily.

The Shanghai-based airline issued a statement yesterday to remind passengers that children aged 2 and over need a ticket and must be accompanied by an adult. Even an infant who does not occupy a seat needs an infant ticket.

The airline said it was also investigating the incident with the Beijing airport authority and the agent company which manages passengers.

The parents of the child should take the main responsibility, while the ground service company and airport authority should take minor responsibility, said Li Xiaojin, a civil aviation expert with the Civil Aviation University of China.

“Other passengers on the flight can sue them and ask for compensation for the five-hour delay,” Li said.
