A third swastika symbol has been discovered as graffiti on the campus of the University of Alabama in Huntsville.

The first two were found at Morton Hall and third, discovered last Friday, was on the campus greenway, according to Ray Garner, UAH chief of staff.

"UAH police continue to investigate three instances of offensive graffiti that has appeared on campus property," Garner said in a statement to AL.com. "The police believe the vandalism is isolated and is the work of a single individual. No additional instances of graffiti have appeared on the UAH campus since Friday, February 9."

After the first two swastikas were discovered, UAH President Robert Altenkirch issued a statement condemning the graffiti.

"The perpetrator of these acts is very much aware that their symbols of hate and ignorance are not shared by those in this space of progressive learning and growth. Rather than education, their goal is to cause alarm and precipitate a campus reaction that, in turn, fuels their aberrant behavior and need for attention," Altenkirch said in the statement.

The school does not consider the swastikas to be a hate crime because they were placed on public places on campus and not directed at an individual, Garner said.
