A family car belonging to Sinn Féin councillor Kevin Campbell, a former Derry City mayor, has been burned out in an arson attack.
Extensive damage was caused to a blue Renault Megane in the Lislane Drive area in the early hours of Sunday, at about 2.45am.
Three people were spotted running away from the scene.
Police say they are working to establish a motive for the attack and are appealing for witnesses, or anyone with information, to contact them.
Sinn Féin Foyle MLA Raymond McCartney said it must have been a very frightening experience for the family.
“What happened last night was not only an attempt to intimidate an elected representative, but an attack on his family,” he said.
“It follows a pattern in recent years where the homes and cars of Sinn Féin elected representatives and activists in Derry have been attacked and set on fire by cowards in the dead of night.
“Our constituency offices at Ráth Mór were also extensively damaged in an arson attack.”
Mr McCartney added: “The people responsible for this attack on the Campbell family offer nothing but destruction.
“Their desire to intimidate us into silence will fail and I ask the people of Derry to stand with representatives like Kevin Campbell who work every day for a better future for all.”
