Plymouth Rock and other historic monuments are vandalized with red graffiti ahead of the 400th anniversary celebration of the Mayflower arriving

The iconic Plymouth Rock was vandalized overnight in a spree desecrating the site marking the landing of the Pilgrims in Massachusetts 400 years ago.

Officials in Plymouth discovered the vandalism at the rock and other sites around the historic town early on Monday morning.

Workers removed the red spray paint, which included the letters MOF and the numbers 508, from the rock before noon.

Authorities say no arrests have been made and the site was open to tourists.
