Maryland resident Carlos Anthony Hollins has been arrested and charged for allegedly issuing deadly threats against La Plata residents via his personal Twitter account.

“IM NOT GONNA STAND FOR THIS NO. MORE. TONIGHT WE PURGE ! KILL ALL THE WHITE PPL IN THE TOWN OF LAPLATA. #BLACKLIVESMATTER,” Hollins’ now-suspended Twitter account read.

Hollins, who apparently turned himself in, has a criminal record, reports BayNet.com:

Court records show a peace order was issued against Hollins in April of 2014 and it expired seven months later. He was also previously charged with trespassing in 2013. Those cases have been closed. There is no information on when Hollins will be in court for a hearing on this latest charge.

The La Plata Police Department decided to put more officers on the street after Hollins’ arrest, according to NBC Washington.
