Police in New Hampshire say a woman and child were covered in feces after they were trapped inside a portable toilet a teen knocked it over while they were inside.

The Manchester Police Department says it happened in a public park last week.

The young mother called 911 stating she and her 4-year-old daughter had been trapped inside a porta-potty at Derryfield Park after a man pushed it over from behind.

She said they were both covered in feces and bodily fluids.

Heather Hamel of the Manchester Police Department called the incident "traumatizing" for the mother and child.

Responding officers spoke with witnesses who said the 18-year-old suspect and the woman had been arguing near the porta-potty.

When the woman went inside to assist her daughter, he allegedly pushed it over. It landed with the door on the pavement, trapping them inside.

Bystanders quickly ran over to the overturned toilet and stood it up, freeing the two.

The mother and child were not physically hurt by the incident.

Police say it appears the victims and suspect did not know each other.

Officers later identified the suspect as 18-year-old Aiden Studer of Manchester.

Studer was arrested and charged with 2 counts of Criminal Restraint and Criminal Mischief.

He was also charged with Simple Assault on a Police Officer for throwing something at one of the officers at the time of his arrest.
