Swatting is the practice of making a prank call to emergency services in an attempt to bring about the dispatch of a large number of armed police officers to a particular address.

A Lancaster teen accused of making hundreds of swatting calls and offering swatting-for-a-fee services pleaded guilty as part of a plea agreement. Alan W. Filion, 18, pleaded guilty Wednesday in Florida to four counts of making interstate threats to injure the person of another.
