The post says: "The individuals responsible were captured in the act by the Memorial's surveillance cameras which shows a man and woman placing stencils and spraying paint on the walkways to advertise the band [Gorillaz]" and its latest album, Humanz, which was recently released.



The veterans memorial fund posted a video of the vandals on its Facebook page on Saturday, and Philadelphia police released the video Tuesday, asking for the public's help in identifying the couple.



The video shows a man and woman walking into the Vietnam Veterans Memorial park on April 23. The man is then seen spray painting something on the concrete walkways in the park.



The man is white and about 25 to 30 years old. He was wearing a black hat, black shirt, and blue jeans.



The woman is white, also about 25 to 30 years old. She has blonde hair and was wearing a gray shirt and black pants.



Started in 1998 in Essex, England, Gorillaz broke into the mainstream with 2001's "Clint Eastwood," a trip-hop-tinged track that peaked at number 57 on the Billboard Hot 100 that year. Humanz, released April 28, is the band's fifth studio album, and serves as a follow-up to 2010's The Fall.
