Investigators say the attack on Denver's fire chief near the department's headquarters appears to have been random and unprovoked.

Chief Eric Tade was in an unmarked SUV on Tuesday afternoon when a woman jumped into the vehicle and stabbed him in the hand and leg. Tade was hospitalized with minor injuries and was released that evening.

On Wednesday, he described the attack as "a very surreal experience," adding that the scariest part was being trapped and restrained in the SUV. Police say 42-year-old Marlene Zacevich-Rodriguez was arrested on suspicion of aggravated assault.

The Denver Post reports (http://goo.gl/IRBqj3 ) the investigation is ongoing, but detectives say they do not believe Tade was targeted because of his job.

Booking documents do not indicate if Zacevich-Rodriguez has hired an attorney.
