A Chinese man has built a cage for his car to stop thieves kidnapping parts and demanding ransom money. Mr Zhang, of Jilin city, says his car’s computerised engine management system was stolen twice. “Each time I found a note clipped under the wiper, with phone and bank-account numbers,” he said. Each time, Zhang had to wire 500 yuan (£35) to get the part back. He has now built a cage to keep his car safe outside his home.
