A man was arrested last week on suspicion of installing a motion-activated surveillance camera in a west Phoenix dental office's bathroom, police said.

On just one day, the camera captured nearly 20 victims, three of whom were children, court documents said.

Office staffers called police after noticing that Innocent Bradley, 27, was visiting the office frequently without an appointment, asking random questions and spending large amounts of time in the bathroom.

In October, Bradley first visited the office, near 75th Avenue south of Camelback Road, staff members told police. The office is not identified in the documents.

Bradley arrived as scheduled, but when it came time for the appointment, employees could not find him, police reported. An hour later, an office manager knocked on the bathroom door and he answered.

Bradley said he needed a few more minutes and closed the door. He then came out wearing a backpack and went outside to his car, where he left it. Bradley then came back for his appointment, staff told police.

Although most patients don't return for appointments for six to eight weeks, according to the report, Bradley kept coming back unscheduled.

Each time, he would ask a question about dental services, go to the bathroom and stay for as long as an hour, carrying his backpack, employees told police.

On Dec. 5, Bradley arrived for a scheduled appointment and spent about 10 minutes in the bathroom with his backpack.

The next day, he returned and again asked the front desk a question, which he had inquired about in the past, and requested bathroom access.

This time, suspicious of his behavior, staff members told him the bathroom was occupied and an employee went in and locked the door.

Bradley waited in the lobby for a while, then checked to see whether the door was locked and waited outside it, court documents said. When employees asked him to go back to the lobby, he waited again, for about 20 minutes. He left when staff told him he should use a bathroom at a business next door.

When employees searched the bathroom, they found a motion-activated surveillance camera facing the toilet that was hidden in a pipe sleeve under the sink and secured with black tape, court documents said. Staff members called police, who took the camera.

On Dec. 7 and 8, Bradley returned to the office, asked questions and sought to use the bathroom but was told it was out of order and left, court documents said.

Two days later, when he returned, staffers called police again.

Bradley told officers he had been to the office about five times, a lower number than staffers estimated, according to court documents.

Although he initially denied knowing about the camera, he later said he knew it was under the sink, police reported. When officers told him they would swab the camera for DNA, Bradley told them he had found the camera and touched it, but did not report it because he was scared, documents said.

Police recovered a data storage card from the camera that contained videos of 17 people using or inside the bathroom on one day. Three were children and nine were employees, court documents said. So far, police have identified 13 of the victims.

Police determined the videos were filmed Dec. 5, the last day Bradley had been allowed to use the bathroom.

When police viewed the office's security footage outside the bathroom from that day, they saw Bradley arrived, went to the bathroom and left after about 10 minutes carrying his backpack.

The office's security footage showed the same people entering and exiting in the same order as the hidden-camera footage inside the bathroom, court documents said.

When police arrested Bradley on Dec. 19, he denied any involvement in installing the camera, officers reported. When they searched his house, they found a Kenyan passport and asked the court to consider him a flight risk.

The court ruled Bradley could be released on bail with an ankle monitor. His next court date is Jan. 2.
