CORPUS CHRISTI, Texas (AP) — Corpus Christi police say 16 suspects have been arrested in a synthetic marijuana sting targeting sales in the downtown area near City Hall.

Police and federal agents made the arrests Wednesday as part of a three-month undercover operation leading to warrants for two dozen suspects.
