Police are investigating a burglary after 10 Chinese paintings and pieces of calligraphy were stolen from a village house in Tung Chung on Lantau Island on Monday, but no other valuables in the home were missing.

A 39-year-old man called police to report that 10 works of art he had collected were missing when he returned the house in Sheung Ling Pei on Tung Chung Road at 7pm, Headline Daily reported.

After investigating, police said they believed the thief may have known the owner of the house because the doors and windows had not been forced open. Officers think the thief used a key to enter the house and steal the artworks, Sing Tao Daily reported.

Officers will check surveillance camera footage in nearby buildings. The owner of the house, a chef at a fast food shop in Tung Chung, moved to the village one month ago with his wife, daughter and two other relatives. He hired a close friend to renovate the house before they moved in.

The man moved to Hong Kong from Guizhou province in southwestern of China last year and was fond of Chinese paintings and calligraphy. In the past few years, he had been collecting drawings and spent a total of HK$150,000 (US$19,115). He expected the value of the artwork to appreciate in the future.
