OXON HILL, Md.- Firefighters say an electrical shock has injured two people at a Maryland resort near Washington, D.C.

The six-year-old girl who was critically injured by the shock is still in critical but stable condition, according to Deputy Fire Chief Alan Doubleday.

Prince George’s County fire department spokesman Mark Brady tweeted that the two were shocked on Tuesday, shortly before midnight, at the MGM National Harbor in Oxon Hill. He says both were taken to hospitals.

News outlets report there were few details immediately available about how they got hurt.

Brady says one person suffered critical, life-threatening injuries and that the other person’s injuries were not life-threatening.

The MGM resort is on the banks of the Potomac River and has a casino, dining, entertainment and stores.
