The attack happened in the town of Gakara close to the Nigerian border, the security source in the region said.
"Boko Haram shot 15 people dead... And kidnapped eight people three of whom were returned on Friday," added the source, who wished to remain anonymous.
A total of 35 houses were torched in the attack which happened around 11:00 pm (2200 GMT) according to a local vigilante group member.
"There were many of them," said the source.
Gakara is just a kilometre (half mile) from the Nigerian border town of Kerawa where the Boko Haram Islamists have long been in control.
The violence has spilt into neighbouring Niger, Chad and Cameroon.
