Birmingham police are looking for three young men who they believe are behind a string of recent thefts at Seaholm High School.

According to police reports, officers responded to Seaholm Wednesday to investigate several incidents of theft, including claims that a car and locker had been broken into sometime after school.

One incident involved a car parked in the Seaholm parking lot that was found by its owner with its door open, police said. Missing from inside were a laptop with its black canvas case, three checkbooks and two Qdoba gift cards. According to police, there was no sign of forced entry.

In a separate incident that afternoon, police say a Sprint HTC Evo cell phone and a red G-Shock watch were stolen from a backpack in one of the school's locker rooms, while an iPhone 4 and brown Fossil wallet were stolen from a locker in the same locker room.

According to police, a surveillance video taken near the time of the thefts shows three young men entering the locker room. All three are described as black and between 15 and 25 years old.

• The first is described as being between 5'8" and 5'10" and weighing 140-170 pounds, wearing a black Northface jacket, a grey hooded sweatshirt, black hat, blue jeans and black shoes.

• The second is described as being between 5'6" and 5'8" and weighing 150-180 pounds. He was seen wearing a black White Sox jacket, a white shirt, grey hat, tan pants and tan shoes.

• Finally, a third suspect is described as being between 5'9" and 6 feet tall, weighing 150-170 pounds. He was seen wearing a black jacket with a hood, a dark green hat with a white block letter "S" and blue jeans.

While the three young men were seen near the locker room near the time of the thefts, police aren't sure if they were involved in the parking lot theft as well. Police do not believe the three young men to be students.
