A Texas man has been arrested and charged with hiding explosives under toilet seats at Bexar County car washes that went off and injured three people, one of them a child.

Police said that Paul Moses Alden booby-trapped toilet seats with commercial fireworks at two car washes. The booby-traps were desisgned to explode when pressure was applied, KENS reported.

Investigators said surveillance footage showed Alden going into and then leaving the restrooms, then watching from the lobby until the explosions took place and leaving the facility.

Employees said they identified Alden because he was a regular customer who had a membership card.
