Two people are in custody after a fire in North Charleston led to the discovery of an active methamphetamine lab Sunday night, according to Charleston County Sheriff’s Office.

North Charleston firefighters called deputies after responding about 9:30 p.m. to a residential home fire at 1903 Jessen Ave., Maj. James Brady said. Investigators determined that an active meth lab was being operated in the home and caused the fire, he said.

Metro narcotics detectives secured a search warrant for the residence and, upon investigation, arrested James G. Osborne, 24, and Jessica R. Tobias, 24, both of the Jessen Road address, on charges of manufacturing methamphetamine, and possession of a firearm during the commission of a violent crime, Brady said.

Osborne and Tobias are being held at the Sheriff Al Cannon Detention Center. Bond hearings are scheduled for today at 3 p.m.
