daughter taken away

my friend has a daughter. Before, he was in good terms with the father of the child (they are not married). Since the father doesnt have work, they agreed that the dad takes care of the child whle my friend works. My friend even rented an apartment for them, so that she can visit her child every other day. They had a fight later on because my friend learned that the father of her daughter lets other girls sleep in the apartment. The guy took off with her daughter (without my friend's knowledge) and she doesnt know where to find them. My friend already sought for the help of the guy's parents but they refuse to give information. She also sought help from DSWD but was told that she has to know first where the guy and his daughter is before they can help. My friend of course went to DSWD because of the fact that she doesnt know what to do and where to find his ex and his daughter. What can she do?what are the steps she needs to take?

this is more missing persons case than a legal one. she can go to media, the police, nbi. search through social networks.

thing is the parents and relatives of the father know where they are they just dont want to tell my friend so she cant take her daughter back

she can file a criminal case and just allege the address of the parents as his address.

what criminal case can she file?

kidnapping, VAWC, failure to return a minor
