An overloaded power strip was to blame for the May 10 fire at the Brooklyn Criminal Court building that injured several firefighters and others on site, according to the Office of Court Administration.

The fire, which was discovered at about 4 p.m., was accidental, OCA spokesman Lucian Chalfen said, and occurred in a sixth-floor storeroom that was not used for record storage.

As of Tuesday, the sixth floor of the courthouse remained closed.
