Hastings was released from the hospital and arrested on outstanding warrants, including one charge of making terrorist threats.
Slaton Police say Hastings was shot in the arm around 1:30 Thursday afternoon while walking down the street in the area of 6th and Panhandle Street.
According to police, Hastings then ran to a nearby house to seek help. That's where police and EMS responded.
The shooting took place near a Slaton ISD campus, prompting police to place the school district on lock down until they could make an arrest.
After three hours and no arrest, school was dismissed as usual with the help of Slaton Police.
Hastings was taken to UMC with non-life threatening injuries and was released late Thursday afternoon.
The Lubbock County Sheriff's Office took Hastings into custody immediately upon his discharge from UMC.
