A man has been charged with murder after a 55-year-old was found dead with a cut on his head in the basement of a Brooklyn deli early Friday.

The suspect, 19, was arrested Monday after Hisham Zidan was pronounced dead inside 797 Deli on Stanley Avenue in East New York, police say. 

It's not clear how Zidan was killed.

The NYPD said Saturday that investigators were looking for three suspects in connection with Zidan's death.
