After a week of evading staff and sophisticated customs equipment in the nooks and crannies of a Stockholm aquarium, a king cobra returned to its enclosure on its own, officials said on Sunday.

"We got him back!" the Skansen Aquarium said in a statement Sunday.

The snake, named Sir Vas, slithered off last weekend through a lamp fixture in a terrarium where he had been brought to a few days earlier.

Following the disappearing act, the venomous vagrant was renamed Houdini, in honor of the famed human escape artist. "It turned out that he had given up and crawled back to his safe and warm home," the aquarium said.
