In case you see suspicious activity and want to report it, state police have an app for that.

Police announced the release of the "See Something, Send Something" app for smartphones on Thursday.

The app allows users to report suspicious activity that may be linked to terrorism, police said in a news release.

Tips will go to the Pennsylvania Criminal Intelligence Center to be evaluated by analysts and assigned for investigation as warranted.

The application, which is available free to iPhone and Android phone users, also includes information on what to look for and when to report suspicious activity, and how to receive important alerts, the release states.

Factors such as race, ethnicity, national origin, or religious affiliation alone are not suspicious activity. Because of that, residents should report only suspicious behavior and situations, such as an unattended backpack in a public place.

In addition to the new mobile app, residents can call the toll-free State Police Terrorism Tip Line at 1-888-292-1919 or email to report suspicious individuals or activity.

In the case of an immediate threat or emergency, call 911 immediately.
