"There's food, trash, drug deals," said Jawaid Bayzar, who added "In the alley we get, ya know, the defacation, drug needles, prostitution" behind his internet company, Forethought.net. One night an employee was sitting in his car when someone smashed the window and tried to stab him, according to Bayzar.

And when Bayzar and his crew stopped cleaning up the constant hazardous mess left by the vagrants, telling CBS he's not equipped to deal with it, Denver fined him.

"If the city's not going to enforce laws against trespassing, or camping, or public defecation and just make me bare the cost of these problems that's just not right," he told CBS4.
