The 8 surveillance cameras at the Jiangcun Residential Area covered both the entrance and exit as well as the two e-bike parking spots inside and outside.
The indoor e-bike parking spot was equipped with a rain shelter, while the outdoor one was in the open and street-facing, but that didn't deter the thieves.
After watching the video surveillance for a long time, Mu Zhiyang and Jiang Yuan noticed that there were only three people who came to steal electric scooters.
One was a man in a raid jacket who might have left fingerprints underneath the I-beam. He looked to be in his twenties and mostly used a master key to violently unlock the bikes. After coming several times, he no longer showed up, probably fearing he would be recognized by security.
