A Renault Scenic car and a Peugeot 107, both black, were set on fire after 3am on Monday on the Limestone Road.The PSNI said the fires were started deliberately.They belonged to community worker and mother-of-three Leanne Marshall and her student daughter Shelley.Leanne said that she woke up in the early hours of the morning after hearing loud bangs."When I looked out the two cars had been set on fire," she said, adding that she didn't know why she had been targeted.She described those responsible as "a disgrace," saying they had "no place in society."Her daughter Shelley added: "I'm just shocked and appalled that it's happened, to be honest. It's just uncalled for."I was angry this morning but I think now I am just ashamed. This is the community I've lived in, grew up in."It is believed the attacks are the result of a loyalist feud in the area.Earlier this month, a pipe bomb was thrown at a parked car in the nearby Duncairn Gardens sparking a security alert.Army bomb disposal experts, who attended the scene, declared the device to be viable. Police enquiries into this incident are ongoing.John Howcroft, of the Ulster Political Research Group (UPRG) in north Belfast, denied that there is a loyalist feud in the area, but said the tensions were between communities and criminal elements.He told UTV that Ms Marshall had been involved in community work in the Tigers Bay area for several years.He said that she has "put so much into the community.""She's involved in some of the most progressive work in the moving of this community forward including the opening of the Alexandra Park peace gate..."He continued: "This is nothing to do with a feud. This is criminal elements opposed to the positive work that's going on within communities - that's why people like this are being targeted."He said the perpetrators are "not loyalists and bring shame on the very word loyalist with attacks like these."Investigating officers have appealed for information and can be contacted on the non-emergency number 101.
