The NYPD wants to teach this suspected Brooklyn school burglar a lesson.

Cops are looking to catch up with an unidentified woman who broke into the Bais Yaakov Academy Jan. 4 in Midwood and took off with a set of janitor keys, authorities said.

The mystery woman gained access to the Elm Avenue private school by “breaking into a back door” at about 9:30 p.m., cops said.

The woman — clad in a black top and jeans, and mask dangling underneath her chin — can be seen exiting the back door of the school kitchen/cafeteria on a surveillance video released Saturday by the NYPD.

Bais Yaakov Academy is a private, all-girls, Jewish school and has 874 students in grades PK, K-12, according to niche.com and greatschools.org.

Anyone with information in regard to this incident is asked to call the NYPD’s Crime Stoppers Hotline at 1-800-577-TIPS (8477) or for Spanish, 1-888-57-PISTA (74782).
