Officials suspect smuggled synthetic marijuana is to blame.

A prison system spokeswoman says officials are checking out “a small number” of reports of sickened inmates.

Inmates have been allowed access to showers and phones and limited time outside their cells in recent days.

Officials hope to lift the lockdown early next week.
