LAKE CHARLES (AP) — Calcasieu Parish authorities say 18 people arrested as part of a 1 1/2-year long investigation were funneling “lab quality” methamphetamine into the area.

The investigation, dubbed “Operation Havana Speed,” involved several people with ties to horse racing. The American Press reports the operation’s results were announced this week.

On Monday, officers began arresting suspects in Louisiana and Texas. Lake Charles Police Chief Don Dixon says 11 search warrants resulted in the seizure of “pounds” of crystal meth, several weapons and the discovery of three active meth labs.

Dixon says of the suspects arrested, most had some tie to horse racing — either as an owner, a jockey or a trainer. The information has been turned over to the Louisiana Racing Commission for further investigation.
