A Universal Studios employee who worked in costume as Captain America sent sexually explicit photos and text messages to an underage girl he met at the Florida amusement park, according to police.

Cops Wednesday arrested James Weldon Alton, 29, on a felony charge of transmitting harmful material to a minor. He was booked into the Orange County Jail, from which he was later released after posting bond.

Alton is seen at right posing with a Universal Studios visitor (who is not the underage victim).

According to an arrest affidavit, the 16-year-old girl met Alton several weeks ago at the Orlando park, where the teen posed for a photo with the costumed worker. The girl later posted the photo online, where it was found by Alton, who “commented on the photo, and an online friendship began.”

The girl told Maitland Police Department investigators that she initially exchanged texts with Alton “as friends,” but that their communication soon turned explicit. Alton sent the teenager a photo of his penis, as well as texts about masturbation and “getting into her,” according to the police affidavit.

In an April 18 text, the girl told Alton she was 16. A week later, “Mr. Alton sent photos of his penis” to the girl’s cell phone.

Police began investigating Alton this week after being contacted by the girl’s father, who learned that his daughter was planning to meet with Alton after school this week. When confronted by her father, the teen admitted exchanging inappropriate text messages with Alton.

When cops interviewed Alton, he acknowledged that he had talked with the girl about her being under 18, though he “chose to disregard this because at times he thought it was a joke or that it was all just merely an online flirtatious relationship.”

Alton (seen in the adjacent mug shot) termed his decision to send the girl photos of his penis as “poor judgement on his part.” After being arrested, Alton “stated again he did not know what he was thinking when he sent the photos of his penis.” Alton also claimed not to know “what he was expecting to receive from sending the photos.”

An Instagram search showed that Alton this month has “liked” photos on the pages of two young women with whom he recently posed at Universal Studios. In a photo on one woman’s page, Alton wrote “Definitely my fav of the day!!” and “You’re a sweetie.”

Following his arrest, Alton was suspended by Universal Studios. According to his LinkedIn profile, Alton has worked for the company since November 2010, and has also been employed as an actor by the Walt Disney Company.
