MYRTLE BEACH — Two teens accused of making separate bomb threats at Horry County schools this week were in court Wednesday, and both will remain in custody at the Department of Juvenile Justice in Columbia through the holidays.

The students, 15 and 16, were charged with conveying false information to police regarding the use of a destructive device following bomb threats.

No explosives were found and no one was injured.. A 15-year-old boy from Myrtle Beach High School, arrested for a threat that forced three school evacuations on Tuesday, asked for a new lawyer Wednesday, said assistant solicitor Mike Freeman.

The 16-year-old from North Myrtle Beach High School pleaded guilty to writing a threat on a school bathroom wall on Monday. He was sentenced to an indeterminate sentence not to exceed his 21st birthday.
