INDIANAPOLIS (AP) – Indianapolis police warn that it's risky to send party invitations on social media where anyone can see those invitations.

The Indianapolis Metropolitan Police Department says such invitations on Twitter, Facebook and Instagram can lead to gatecrashing, underage drinking, drug use, physical assaults and civil liability for homeowner if anyone gets injured because of illegal activity.

The department says all parties should have a sober and responsible adult present at all times monitoring all activities. Police also recommend that parents monitor their children's social media activity.

Police say that if uninvited guests arrive and begin to cause problems, those hosting the party should notify police as soon as possible.
