Police in Toronto say they have identified the builders of a mysterious tunnel and say there was no criminal intent.

Police said in a statement Monday that two men told investigators they built the tunnel for "personal reasons." Police investigators verified their account and are satisfied there was neither criminal intent nor any threat to the public. Police say they received information about the builders last Friday. Police didn't' specify who built it or why.

Police had asked for the public's help in trying to determine who built the mysterious tunnel near York University.

The tunnel was 10 meters (10 yards) long and two meters (two yards) high.

The chamber was discovered Jan. 14 in a secluded wooded area by a conservation officer.
