A Current Affair reporter Ben McCormack has been admitted to hospital days after he was arrested and charged with using a carriage service to send child pornography material.

The 42-year-old went to hospital on Monday for a mental health assessment.

Last week, he was arrested by detectives from the sex crimes squad at Moore Park as he drove to work.

Police searched his home and ACA's offices in Willoughby on Thursday before he was charged and released on strict bail conditions.
