Sanitation workers ploughed through five tonnes of rubbish at a collection depot in Shanghai to help a woman find her lost mobile phone, a news website reported. The woman from Beijing was in the city for a meeting and lost her mobile in a restaurant near the City God Temple, Thepaper.cn reported.

But by the time they got there the bin had been emptied and the signal lost as the trash was taken away by truck. The couple contacted the sanitation department and 16 workers searched through a huge mound of collected trash, the report said. The search was made more difficult because the phone’s ringing tone had been turned off. The phone was lost at lunchtime and found by the workers at 3pm. The head of the sanitation workers was quoted as saying: “There was too much garbage and we didn’t have enough space to dump it, so we had to use the road beside the garbage station.
