EUREKA  (AP) — Eureka authorities say a 2-year-old boy was badly burned and his parents were arrested following an explosion in an apartment where hash was being produced.

The Eureka Times-Standard reports the explosion happened Friday night at an apartment where officers found equipment used to extract hash from marijuana plants. The apartment was badly damaged but did not spread to other units.

Officials said Saturday the toddler had first- and second-degree burns on his face, front, back, arms and legs. He was airlifted to a hospital in Sacramento.

Police say the parents, 21-year-old Logan Danny O’Neal Hughes and 19-year-old Andrea Marie Ruiz-Guerrero, suffered less serious burns. They were arrested on suspicion of child endangerment and taken to county jail following treatment at a Eureka hospital. Bail was set at $50,000 each.
