Police investigating a pipe bomb attack in Derry last month say they want to speak to a couple seen in the area at the time.
A PSNI spokeswoman said the male and female were seen in the Charlotte Street area on October 22.
“At approximately 10pm the device was thrown at the patrol car but missed its target and fortunately did not detonate.
“The couple were wearing dark clothing and the female had long dark hair.
“This couple may have witnessed the attack and police are keen to speak with them,” she said.
A number of residents were forced from their homes overnight after the attack which, the city’s PSNI area commander said was designed to seriously injure or kill.
Speaking at the time Chief Inspector Jon Burrows told the ‘Journal’: “It was a viable pipe bomb, army technical officers described it as a device capable of causing serious injury or death. Thankfully it didn’t detonate.”
Anyone with information is asked to contact police on 0845 600 8000.
