Hundreds of people were campaigning in the Indian capital Delhi on Thursday, calling on Prime Minister Narendra Modi and his ruling Hindu nationalist party BJP to do more to protect Christians under attack.
The protestors began holding up signs saying: "Enough is Enough, What are police doing?" outside the city's main church. They then began marching towards the Home Minister's house, when police started apprehending them.
Vandals have attacked churches on five separate occasions since December.
In the first attack, criminals set fire to St Sebastian's Church in eastern Delhi, destroying the entire inside of the building.
Police initially said the fire was caused by a "short-circuit", but after hundreds of people protested they launched a criminal investigation.
In the most recent attack, vandals broke into St Alphonsa's Church in Vasant Kunj, south Delhi and destroyed objects used for holy communion. The communion cup was also stolen.
Police say they've provided protection for more than 200 churches in Delhi.
In regards to the arrests, senior police officer MK Meena told the NDTV news channel: "They have no permission to protest on the road.
"They can't just march to the home minister's residence. We have to protect the homes of VIPs."
