A 33-year-old man was arrested early Sunday morning after hijacking a taxi cab by threatening its driver with a knife.  According to police reports, the cab driver, a 54-year-old man, picked up the suspect near 15th and Guerrero streets some time around 3:10 a.m. The suspect then pulled out a knife and forced the cab driver to take him home. The victim drove several blocks before fleeing the cab.

The suspect then ran over to another car, jumped in the back, and began threatening its 46-year-old driver. After the latter kicked the suspect out of his car, the suspect pulled out his knife and damaged the outside of the car door.  Police arrested the suspect upon arriving at the scene.
