Bicycle detail

Arrived home at 7 pm Wednesday April 20 and saw that this bike and two others (an identical bike for the other kid ad the mother's bike) had been taken. They were locked together by cable to the staircase leading from patio up to terrace. Lock and cable were gone, too. Likely entered through gate from alley in back; no lock on gate. Last time we know bikes were there was Sunday evening April 17, so unsure exact time/day of incident. Thieves left one other bike which was locked separately to different part of staircase. That bike was secured with the same cable and Master lock as the stolen bikes, and thieves had started/attempted to cut that cable too. Unclear why they stopped, but that bike was additionally secured with Kryptonite brand lock and cable, so they might have decided it was too hard to get that bike and went with the other three.
