A late night confrontation between members of the occupy movement and St. Louis Police ends with several occupiers arrested  and the group accusing St. Louis police of using violent tactics.

Compton Hills Reservoir Park on Grand just South of I-44 is where a  showdown between police and protesters happened Thursday night. The conflict culminated the first day of an occupy the midwest conference in St. Louis.

Several occupy protesters had set up an encampment at the city park. That violated the city`s 10pm park curfew. About 150 protesters were at the scene as police tried to break up the gathering.  A release from the occupy the midwest movement says at least 12 people were arrested and that several were visibly bloodied.  The release says St. Louis used pepper spray and violent tactics.

Grand was apparently shut down for some time during the confrontation and the window of a police cruiser was broken.

We have called St.  Louis police this morning for comment but so far have not received anything.

Earlier in the day, Occupy Midwest protesters took to the streets of downtown St. Louis. The crowd marched to the Bank Of America building downtown. Protesters also plan to demonstrate against Monsanto this weekend.

The Occupy The Midwest regional conference being held here in St. Louis runs through Sunday.
