UPDATE: Cleveland Police have denied reports that they received calls from neighbors regarding Castro's house.

As the story of the three missing Cleveland women rescued from a house on Monday unfolds, details are coming out about previously reported incidents that allegedly weren't taken seriously by police.

USA Today and the AP have anecdotes from neighbors about the strange things they saw at suspected kidnapper Ariel Castro's house.

Here are some of the clues that something was amiss with Castro:

A neighbor who lives three houses away from Castro said her daughter saw a naked woman crawling in Castro's backyard several years ago, according to the AP. She called police, but they "didn't take it seriously," the woman said.

The AP reports that another neighbor, Israel Lugo, said he heard pounding on doors and saw plastic bags over the windows of the house a couple of years ago. Police officers didn't get an answer at the front door of the house, and left after walking to the side of the house.
