Baytown police arrested three teens accused of robbing people at gunpoint.

Juan Nava, 17, was arrested along with a 15-year-old and 16-year old.

Their names have not been released because they are minors.

"They were essentially on a crime spree," said Lt. Eric Freed with the Baytown Police Department. "Fifteen and 16 is very young for this type of violent behavior."

Freed told Local 2 the three teens robbed people at gunpoint while wearing bandanas that covered their faces. 

Police said the first robbery happened on the 600 block of West Main Street and another happened at 3321 Market Street. About a week later a man was carjacked on Stimson Street in Baytown. 

Baytown police believe the three suspects are responsible for at least five aggravated robberies.

In one of the crimes, the victim had his cell phone stolen. The phone was equipped with an app that takes a photo when someone tries to break into the phone and doesn't know the password. It was programmed to then email that photo to the phone's owner. Police used it to track down one of the suspects.

"He was cooperative," said Freed.  "He implicated the other two suspects in the case."

All three of them have been charged with aggravated robbery.
