SOUTH PHILADELPHIA (WPVI) -- Crews worked quickly Wednesday to remove vulgar and offensive graffiti spray-painted on homes and sidewalks in South Philadelphia.It happened along the 2100 block of South Bouvier Street.One of the homes vandalized is owned by Charlie Inverso.Inverso says this kind of behavior is reprehensible."That upset me because what are they doing? How safe am I? What is the reason?" Inverso said.The people responsible hit at least five properties in the South Philadelphia neighborhood, spray-painting images from the old Soviet hammer and sickle to a message encouraging violence against police officers.The vandals even used a stencil with the message "It is right to rebel" alongside an image of a Molotov cocktail.Neighbor Nouha Bali says she has lived in the area more than 30 years and this is the first time she has seen anything like this.In fact, she says this should serve as a wake-up call for this neighborhood."Time to act responsible, have more responsibilities towards our community," Bali said.Police are talking to local business owners as there are a number of surveillance cameras in the area.Anyone with information is asked to contact police.----------
