Police in Brooklyn have charged the man they were questioning in the Brooklyn mezuzah arsons.
Police say 35-year-old Rubin Ubiles is charged with hate crimes in connection with those mezuzah burnings.
The charges include 12 counts of burglary as a hate crime, 12 counts of arson as a hate crime and 12 counts of criminal mischief as a hate crime.
Authorities say Ruben Ubiles, 35, was seen on surveillance cameras lighting a match in one of the buildings, and investigators have video of him inside both buildings at the time of the crimes.
A law enforcement official tells NBC 4 New York that Ubiles has also made statements implicating himself.
Police say part of the way Ubiles was tracked down was through facial recognition of his ear, caught on the security camera.
They put the photo in the police facial recognition database, which matched Ubiles to an old picture of the side view of his head.
Ubiles is being evaluated at a hospital and information about an attorney wasn't immediately available.
Police would not say why he was taken to a hospital.
