The Black Lives Matter street mural in front of Trump Tower in midtown Manhattan has been vandalized three times in one week, according to the New York Police Department.

“It is absolutely unacceptable that the mural to commemorate the Black Lives Matter movement was vandalized, and we will absolutely fix it,” Julia Arredondo, a spokeswoman for Mayor Bill de Blasio, said in an email.

The latest incident occurred Saturday afternoon when two women from Staten Island, ages 39 and 29, were arrested after they were seen pouring paint on the mural, the department said.

When an officer attempted to approach one of the women, the officer slipped and injured his head and arm. He was taken to Bellevue Hospital and is in stable condition, the NYPD said.
