A 17-year-old gay student who brought a stun gun to school to scare away bullies has been expelled.

Update: 11:10 a.m. ET: Darnell "Dynasty" Young and his mother, Chelisa Grimes, found out late Monday that Young cannot finish his junior year and he will miss the first semester of his senior year, The Indianapolis Star reported.

"I couldn't believe that they did it," Grimes said. "They really kicked him out."

Grimes and Young can appeal to the Indianapolis Public Schools school board and the courts if necessary, but Grimes said they're still weighing their options. Young said he plans to get his GED and go to college.

An Indiana mother sent her gay son to school with a stun gun to protect him against bullies. The teen now faces expulsion, but the mother says she would do it again.

Darnell "Dynasty" Young, 17, was facing daily harassment from bullies at Arsenal Technical High School in Indianapolis who would taunt him, throw rocks and bottles at him, spread rumors and follow him home, The Indianapolis Star reports.

After reporting the bullying to the school more than 10 times, his mother, Chelisa Grimes, said she gave Young a stun gun for protection, because school authorities weren't doing enough, MSNBC reports.

"I do not promote violence -- not at all -- but what is a parent to do when she has done everything that she felt she was supposed to do ... at the school?" Grimes told CNN's Don Lemon on Sunday. "I did feel like there was nothing else left for me to do, but protect my child."

Young said he carried the stun gun in his backpack for a few weeks without using it, the Star reports.

On April 16, when six students surrounded him at school calling him names and threatening to beat him up, Young pulled the stun gun from his backpack. He raised it in the air, setting off an electric charge and sending the group scurrying, CNN reports.

"I brought the stun gun 'cause I wasn't safe," the Young said.

School police officers arrested Young and took him away in handcuffs. School officials are investigating the incident, but none of the students who allegedly surrounded Young has been positively identified, CNN reports.

The school district held an expulsion hearing last week but no decision has been announced, CNN reports.
