A swim coach has been arrested for allegedly sending inappropriate text messages to a 13-year-old girl on his team.

Bridgeport police say they took 28-year-old Alan Marcel into custody Wednesday. They say the victim's mother discovered the sexually explicit texts on her daughter's phone.

Officials at Fairfield Ludlowe High School say they have "severed ties" with the instructor after learning that he was accused in the incident, which involved a member of a different swim team that he coached in Bridgeport called the Park City Wolfpack. News 12 Connecticut interviewed Marcel last year for a story about the Park City Wolfpack, which he described as a competitive swim team for kids from the greater Bridgeport area.

Parents at Fairfield Ludlowe High School say they received an email on Thursday telling them that he was no longer a swim coach at the school as a result of an ongoing investigation. Both police and parents say they were shocked to learn about the allegations.

Marcel was arraigned on a charge of endangering the welfare of a child. His bond was set at $20,000.
