After a Teen Mom exploded on the air, authorities launch investigation into charges of abuse!
RadarOnline.com reports that one of the Teen Mom stars Amber Portwood exploded  at ex-fiance Gary Shirley, hitting and kicking him multiple times as their infant daughter stood at their feet.
An investigation by the Anderson Police Department in Indiana was launched after the 20-year-old mother was shown on the popular MTV show being violent in the presence of a child during an argument.
"We were made aware of the domestic abuse following the episode that aired on MTV," Anderson Public Information Officer Mitch Carroll said.
"Based on that there was a case drafted and a detective was assigned. The Department of Child Protective Services in Indiana notified us that they had been aware of the incident as well."
The altercation between Portwood and Shirley ensued after he accused her of being a bad mom and threatened to report her to Child Protective Services.
"Once the detective reviews the initial case report...there will need to be interviews conducted with Amber and Gary," Carroll said. "Anytime you have photographic or video evidence it helps."
