Allowing your kids to play on scooters outside the house on a quiet street seems innocent--and common--enough. But a Texas mom was arrested and spent the night in jail after a neighbor complained that the children were unsupervised.

The parent, Tammy Cooper, disputes the "humiliating" charge, saying she was watching the kids, ages 6 and 9, the whole time from a lawn chair.

But police took the neighbor at her word, and a few hours after the call, arrested Cooper for child endangerment. Cooper told KPRC that the arresting officer told her, "We're here for you."

The accused parent spent the night behind bars. "Orange jump suit, in a cell, slammed the door, for 18 hours," she said.

Cooper is suing the La Porte Police Department, the officer, and the neighbor who made the call. In a statement, the police department said it was "confident of the known actions of the officers on the scene that evening." The neighbor had no comment.
