The Philippines National Police Criminal Investigation and Detection Group arrested Alexander Llagas for sexually abusing his three daughters aged 15, 10 and six.
The complaint stems from the paternal grandmother asking the local police for help in arresting Llagas due to the abuse.
51-year-old Llagas, a widower, impregnated his eldest daughter who had a child last September.
The complaint also said that the suspect molested his other two daughters – prompting the grandmother to seek help in arresting her son-in-law.
All three girls were handed over to the local Social Welfare and Development Office in Cateel. Their father has been detained at the Cateel police station, he is facing multiple criminal charges.
