The men were arrested yesterday in a case which has provoked expressions of outrage in Pakistani newspapers, several of which have suggested a politically-influenced cover up.
At least 280 children were filmed being sexually abused by a gang of 25 men who used the hundreds of videos they produced to blackmail the youngsters' parents, according to a lawyer for the victims.
The village at the heart of the scandal, Hussain Khanwala, lies in the Punjab stronghold of the ruling Pakistan Muslim League-N (PML-N) party.
Saeed said these five men would join seven others who are already in police custody following the scandal.

Local police spokeswoman Nabeela Ghazanfar confirmed the details.
Shahbaz Sharif, the chief minister of Punjab province where the abuse took place, has ordered an independent judicial inquiry and Prime Minister Nawaz Sharif has vowed stern action against those responsible.
An initial police probe, carried out last week at the behest of the provincial government, described the allegations as "baseless" - a conclusion immediately rejected by local media and rights activists.
The abusers allegedly tried to extort money from parents of victims, selling clips of the videos locally for 40 Pakistan rupees each (around 40 US cents) if they did not pay up.
