So they say Sambala let himself out of the apartment, took the elevator to the ground floor, and walked two blocks in search of his playmate.

“It was very scary,” said Sambala’s mother, Alima Kante.

Other people who live in the 1700 block of North Spaulding Avenue, including Maurice Sanford, stopped to find out what he was doing out by himself, dressed only in a T-shirt, underpants and Spider-Man flip-flops.

“He was shaking. He looked like he was nervous,” Sanford said, “and then I tried to ask him questions and he wouldn’t answer me.”

Police went going door-to-door Sunday trying to find Sambala’s family. Finally, later Sunday morning, Sambala was reunited with his mother and uncle.

He had been taken to St. Mary of Nazareth Hospital for a medical evaluation, but was reported to be in good condition, the Sun-Times Media Wire reported.
