DETROIT, Dec. 29 (UPI) -- A woman walking backward while talking to a man fell into a 5-foot deep sinkhole in the middle of a street in a Detroit suburb.

Police said the man tried to warn her, but it was too late, the Detroit Free Press reported.

The woman was treated for minor scrapes and bruises.

The sinkhole had opened up sometime overnight, apparently caused by water main rupture last week.
