Some people hate the snow, but an off-duty Rockland County Sheriff’s detective is thankful for it. That’s because footprints led him to a man who would be arrested for trying to break into his unmarked car. Published reports said 21 year-old Ahmad Lakes was arrested early yesterday after Sheriff’s patrol officers followed footprints through the snow, spotted Lakes and chased him down. He reportedly faces charges of obstructing governmental administration, resisting arrest and attempted petit larceny.
