In order to thrive in business, he repaired the homemade "steel spikes" to the roadside near his booth, waiting for the car to be sold through the tyres.

In March 10th, eight pairs of "steel spike shoes" and Zhu were arrested on the spot by the Yanjin County police.

Recently, Yanjin County Traffic Police Brigade 219 squadron patrol police often received a driver's complaint, said that every time driving through the provincial road 219, tire will always be thrown on the road above the old shoes pierced.

Yanjin County Traffic Police Brigade provincial squadron 219 quickly launched an investigation.

At 5 a.m. on March 10th, a patrolling policeman found a man on his driveway near the intersection of provincial highway 308 and provincial road 219, throwing his old shoes on the way to the center of the road.

The police then stopped to check it out and found 8 pairs of old shoes with nails on their bicycles.

The man admitted that since the beginning of February 2008, he had thrown the home-made "steel spikes" on the pavement many times at the busy section of provincial highway 219 and provincial highway 308, waiting for the tire burst.
