The number of terrorist and criminal attacks by letter bombs has substantially increased over the last few years.  A bomb is easily disguised in any of countless of ways, but the last thing a bomb is likely to look like is a bomb.  Mail bombs come in all shapes and sizes and can look quite harmless.  A small, very powerful bomb can be concealed quite easily in a small box, package, or envelope.  If you suspect that a suspicious letter or package has been delivered to you, evacuate the area and contact the University Police department at 348-5454 or 911.
