KANSAS CITY, Mo. (AP) — Authorities say they rescued a frail 17-year-old boy whom they found handcuffed to a pole in his parents' Kansas City, Mo., basement.

Police said Wednesday that they are still investigating and haven't submitted a report to prosecutors to consider possible charges.

According to a police report, an officer and social worker found the teen Monday after someone called in a tip. Upon entering the basement they heard someone cry out: "I didn't do anything. I didn't do anything. I didn't do anything."

Police say the teen said he had been confined to the basement since his father pulled him from school in September. They say he looked very thin for his height and desperate.

The report doesn't disclose the name of the teen or his family.
