SAN ANTONIO -- A student at a South Side public charter school was given three days detention after school officials caught him with a cellular phone that allegedly had pictures of "gang-related activities."

Officials at Por Vida Academy called police Tuesday after they confiscated the student's cell phone. The phone has the capability of capturing still photos.

"Pictures of students with drugs, students with guns, and quite a few gang symbols and gang- related activities going on," Por Vida Principal Steven Langseth said.

Langseth said the teenage boy was allegedly showing the pictures to other students.

"What I saw on that phone gives me a good picture of what that kid's life is like," said Langseth .

School superintendent Joseph Rendon said school officials care about their students and it's important to figure out what's happening in a student's academic life as well as their personal lives. Rendon added the incident raised a red flag that signaled that some students may need help with problems outside school.

All types of cellular phones are banned at Por Vida Academy.
