Mailbox Vandalism Since December 30th, SLMPD has observed an increase in the number of calls reporting damage to mailboxes in the area. Some were smashed or knocked off of their mounting posts, and one was destroyed by a small explosion, likely caused by illegal fireworks. Please be alert to noises such as loud banging or fireworks, especially during the late evening and early morning hours. If you see or hear anything unusual, do not hesitate to contact police by dialing 911. South Lake officers will be happy to respond and investigate.
