Police searched a UA library Thursday looking for a bomb, reports stated.

A UA employee was in the second-floor bathroom of the Main Library, 1510 E. University Blvd., when he noticed a drawing of a television set and the words "bomb threat" written on a stall, reports stated.

The library's building director and police searched the building, but found nothing suspicious. An employee told officers that he was in the bathroom on Wednesday and didn't notice the graffiti, reports stated.

Officers photographed the graffiti before library employees cleaned it off the stall. There are no suspects and no witnesses.

Two male students have been calling a female student a "ho" since bid night, the female student told police.

She told police that the men have been calling her since Jan. 31. During the calls the men would curse at her, call her a "ho," or sing songs to her with the word "ho" in the lyrics, reports stated.

The men have allegedly left voicemail and e-mail messages with the female student that are similar in content.

The female student's roommate told officers that she and one of the male students were dating a few weeks ago. The roommate said that she believes he liked the student while they were together, reports stated.

Police tried to call the men, but were unable to speak with them. They plan on trying to contact them again in a few days. Officers told the female student to tell the men to never call again if the calls continue, reports stated.

She told police that she does not know if she wants to press charges, reports stated.

Two UA students were arrested Feb. 4 after they told police they had been smoking pot while inside a car parked in a campus garage, reports stated.

Police were on the first level of the Main Gate Garage, 880 E. Fourth St., when they approached the car and its three occupants. Officers saw one man get out of the car and begin to walk away when he noticed the officers approaching, reports stated.

Police stopped the man and spoke with the car's other occupants. The man in the driver seat, a 19-year-old student, told police that they were just talking, but later said that they had been drinking a little at a party, reports stated.

Officers noticed the man's eyes looked bloodshot and watery and stated that his breath smelled like alcohol. The driver told police they could search his car, reports stated.

Police noticed that one of the passengers, an 18-year-old student, had a bulge in his front pants pocket. At first, the student refused to empty his pockets, but later pulled out a smoking pipe and a baby jar partially filled with marijuana, reports stated.

The 18-year-old told police that he and the driver had been smoking marijuana in the car. Officers found another small jar filled with weed in the vehicle, reports stated.

The students were cited and released on suspicion of possessing marijuana and drug paraphernalia, reports stated.

The third occupant in the car, a female UA student, denied smoking marijuana. Police didn't notice any odor of burnt marijuana on her. She was released from the scene, reports stated.

The pipe, jars and marijuana were taken to UAPD as evidence.

University employees told police Saturday that they didn't know about an emergency action plan after employees discovered liquid nitrogen leaking from a campus tank, reports stated.

The Tucson Fire Department's hazardous materials crew went to the seventh floor of the Optical Sciences building, 1630 E. University Blvd., and inspected the tank. They told police that the tank was venting liquid nitrogen, reports stated.

Firefighters took the tank out of the building where it could vent safely. Building employees told officers there was no action plan in the case of a ruptured tank. The lab director also told police that he didn't know of any action plan, reports stated.

Firefighters said the venting gas was not dangerous, but the tank may have problems that should be looked into. Police called employees from UA Risk Management. They said that they would look at the tank Monday.

Employees in the building told officers that they will have a meeting to talk about the incident, reports stated.
