I was leaving for work when i looked at top of building and observed triangular shaped object, almost translucent with only 3 bright white lights in triangular shaped pattern. unknown object was flying north bound when stopped over building and was hovering for 5 seconds. object glided in no sound manner and changed path going west. i attempted to grab my cell phone and broke visual contact with object. when i looked up object have disappeared. i was cruising in the car observing sky for any additional lights but none were found. down the road than saw unmarked car speeding in same direction towards west flashing blue emergency lights, remark, it was a non-police officer cruiser. car was mostly black colored and had no siren sounded.
