Zhang Zian told the detailed story to the 110 police, from Zhan Tian almost being trapped, to the dog-trappers' attempt to escape and to how they ended up hitting the yard wall. He also showed them Zhan Tian's police dog certificate and the bait used by the dog-trappers.
He was not sure what was in the bait, but it definitely contained an anesthetic. It would be appropriate to accuse them of selling a dangerous illegal substance.
In the end, he emphasized that one of the trapped dogs was a retired police dog. This immediately caught the attention of the police.
Shortly after the case reporting was finished, Sun Xiaomeng arrived along with a few others in a taxi. Zhang Zian didn't know those people, but they might be Mr. Qian and Mr. Li's family or friends. The police instructed them to stay out of the police cordon. They were only allowed inside after Zhang Zian explained it to the head police.
