Authorities say a woman stabbed Denver's fire chief after jumping into his vehicle near the department's headquarters.

Police spokesman Doug Schepman says the woman jumped into Chief Eric Tade's black SUV on Tuesday afternoon and stabbed him in the hand and leg.

Tade, who ran into fire headquarters for help, was hospitalized with minor injuries and was released Tuesday evening.

Police say 42-year-old Marlene Zacevich-Rodriguez was arrested on suspicion of aggravated assault, and that witnesses identified her.

Police are still investigating a motive, and Schepman says investigators do not know whether the chief and the woman knew each other.

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