Late at night, a northbound train roared as it entered a tunnel.
Signal reception is poor in mountainous areas, and even worse in tunnels, so Lin Chunsheng's mobile phone had been out of service.
Even if there had been a signal, he wouldn't have been able to use his phone.
His mobile phone was confiscated this morning in Shenzhen and currently, he's being handcuffed in the train compartment, undergoing interrogation by the joint Special Task Force.
The escort duty was assigned to Old Li, an instructor from the Four Factory Police Station under Linghai Police Bureau. While escorting the three swindlers, it was crucial to interrogate them rigorously before dawn, to pry their mouths open and find out how much they had illegally profited over the years and where the illicit funds were stashed.
