Three men were arrested Thursday in connection with alleged vandalism that caused several thousand dollars in damage to Morro Rock.
Police arrested Gustavo Alejandro Franco, 24, Mauricio Martinez, 19, and Eduardo Antonio Mata, 19, all of San Luis Obispo, on suspicion of felony vandalism after they allegedly sprayed graffiti on the rock in late May.
The three vandals then posted video of themselves committing the crime on YouTube, which investigators then used to establish their identities, police said.
Volunteers and state and city employees worked for two days to remove the graffiti, which was not believed to be gang related, police said.

Franco, Martinez and Mata remained at County Jail on Friday.
