When a family, surnamed Liu, in Southwest China's Chongqing municipality headed out to work on the morning of May 28, they couldn't open the door – it had been glued shut during the night.

Upon investigation, a creepy scene was found on the footage by the surveillance camera installed above the gate, showing a "ghost", cloaked in white satin, groping its way in the dark on tip toes and spending five minutes to glue the door shut at 2:00 am the previous night.

Grandpa Liu said it must have been an elderly woman judging by the figure and movements of the "ghost".

This was not the first time the Lius' door was impossible to open. Similar things happened four months ago.

The police have been notified, but Grandpa Liu said they were hoping to make peace with the people who they might have offended, cfp.cn reported.
