Investigators in Lauderhill, Florida say police have stepped up patrols in a neighborhood where a well-dressed man, armed with a machete, has been showing up on residents’ doorbell cameras in the middle of the night.

Videos appear to show the man knocking on doors, in at least one instance with the handle of the machete, but neighbors say the man takes off before anyone can answer.

The neighborhood is located off of Inverrary Boulevard near North University Drive in Lauderhill.

While Lauderhill police have acknowledged the situation is bizarre, investigators say there is no evidence the man has committed a crime.

Residents in the area were urged to check their security cameras.

Anyone with information about the man is encouraged to relay it to Broward County Crime Stoppers at 954-493-TIPS (8477).
