Minutes before 3 p.m., authorities were dispatched to the First Christian Missionary Baptist Church in the 6100 block of East 38th Street near Arlington Avenue on reports of shots fired.

Police said the SWAT team was called because of the church’s immense size and to secure surrounding areas.

When officers arrived at the scene, the church’s pastor told police that his grandson fired shots at him inside the church.

Police identified the suspect as Calvin Griffin, 19.

Police said the pastor told them that Griffin had been living inside the church and that he asked him to leave because he believed that Griffin was stealing from the church.

As the pastor approached Griffin to demand that he leave, Griffin raised a handgun and pointed it at him. The pastor turned to run, and said he heard one gunshot. He escaped the church unharmed, IMPD Spokesman Kendale Adams said.

The IMPD SWAT team remained at the scene for several hours trying to make contact with Griffin and detectives said he finally surrendered at about 7 p.m.

Griffin was arrested on charges of criminal recklessness and possession of a handgun without a license, police said.
