An uninvited guest reportedly came within 30 yards of Detroit Lions players at Tuesday’s practice.

The unidentified man entered the Lions’ facility through an unlocked gate, walked to the edge of the practice field, and starting shouting at players, including linebacker Tahir Whitehead, according to Kyle Meinke of MLive.com.

After noticing a reporter attempting to record the exchange, the intruder responded by shouting racial slurs. He was eventually escorted out by security.

The incident is under investigation by local police.
