Two campus monitors at Marjory Stoneman Douglas High School have been barred from school property after it was reported one of them warned school staff members that Nikolas Cruz was acting suspicious as he entered the campus on Feb. 14.

Andrew Medina and David Taylor, both sports coaches and unarmed campus monitors, "have received administrative reassignments ... until further notice," a Broward County Public Schools spokesperson told Fox News.

Medina told Coral Springs police in the aftermath of the massacre that unfolded on the Florida high school campus on Valentine's Day that he saw Cruz exit an Uber and enter the campus carrying a black bag, the Sun-Sentinel reported.

The unarmed campus monitor reportedly said that when he saw the mass shooting suspect seemingly "beelining" for the 1200 building — the location where the shooting, which killed 17 people, unfolded — he warned other campus security guards.

Taylor, who Medina said was another unarmed security monitor he contacted regarding his suspicions about Cruz, hid in a janitor's closet when he heard the gunfire go off, according to the Sun-Sentinel.

Andrew Pollack, whose daughter, Meadow, was killed in the shooting, tweeted that after seeing Medina's comments in recent news reports, he "went up to the school and handled it. ... Andrew Medina I'm not done with you."

Fred Guttenberg, father of Jaime, another student who died in the shooting, tweeted that he went with Pollack to the school "to lay out our concerns and to ask for [Medina's] removal. Glad that we got this done."

Pollack added to the news outlet Medina didn't call a "Code Red" — which would've signaled a threat inside the school — when he saw Cruz.

Medina reportedly told police his training taught him only to call a "Code Red" if he saw someone with a gun or saw the shooting himself, and therefore didn't issue the security warning.
