Gov’t watchdog head facing drug charge

CITIZENS UNION head Dick Dadey was arrested early Tuesday on drug possession charges.

Dadey, 59, turned himself in about 8:30 a.m. at the 84th Precinct in Brooklyn Heights, police said.

Rumors of Dadey’s impending arrest spread on Oct. 11, but his reps denied it at the time.

On Sept. 20, he took a leave of absence from the good government group. A police source said Dadey went to a drug treatment facility.

Citizens Union announced Tuesday it had replaced Dadey with former Public Advocate Betsy Gotbaum.

Investigators found the unspecified drugs in his Remsen St. home after serving a search warrant based on an unrelated allegation, police said.

Dadey was charged with drug possession.

Citizens Union officials declined comment Tuesday.

Dadey could not be reached for comment.
