Alexandra Douglas, 23, of 511 Wood Ridge Ave., was charged on a warrant arrest Thursday with second-degree threatening and disorderly conduct.

The charges stem from a Jan. 1 incident in which her 21-year-old sister told police that Douglas had made threats of bodily harm and abuse against their grandmother, who lives with them. Douglas left the house that day before officers arrived.

After investigating the complaint, police felt there was just cause to issue an arrest warrant.

Douglas was released on a promise to appear Jan. 7 in Bridgeport Superior Court.
