His camera shows that Muslims "are blocking the streets with barriers. They are praying on the ground. And the inhabitants of this district cannot leave their homes, nor go into their homes during those prayers."
"The Muslims taking over those streets do not have any authorization. They do not go to the police headquarters, so it's completely illegal," he says.
The Muslims in the street have been granted unofficial rights that no Christian group is likely to get under France's Laicite', or secularism law.
"It says people have the right to share any belief they want, any religion," Lepante explained. "But they have to practice at home or in the mosque, synagogues, churches and so on."
Some say Muslims must pray in the street because they need a larger mosque. But Lepante has observed cars coming from other parts of Paris, and he believes it is a weekly display of growing Muslim power.
"They are coming there to show that they can take over some French streets to show that they can conquer a part of the French territory," he said.
