An American pastor, Ezekiel Ndikumana, has said God helped him know what to do, after a man at the front of his church pulled a gun out and pointed it at the congregation.
Pastor Ezekiel, who has been hailed a hero, was praying with members of his congregation when the incident happened.
He can then be seen on camera tackling the gun-wielding man into the aisle. He held him down until police arrived at the scene in Nashville, Tennessee.
The incident led to the arrest of Dezire Baganda, 26, who police said faces more than a dozen felony aggravated assault charges.
While Baganda is not a member of Nashville Light Mission Pentecostal Church, the pastor said he's attended previous services, according to American new channel ABC.
Akimana Charite, a church member who saw what happened on Sunday, told News Channel 5, Nashville: "We were so shocked seeing him come in the front and pull out a gun. The whole church was calm, we thank God if we started panicking, he may have started shooting around, but we all stayed calm".
