Downpatrick residents have said they feared for the safety of people in the Ballymote Walk area after two cars were set alight in the space of 24 hours.
A burglary was reported in the estate at around 11.15pm on Sunday night, with a grey Mercedes stolen and later found on fire on the Ballyhornan Road.
On Monday, fire crews were called to deal with another car blaze, again on the estate at around 4.15pm.
