A man was charged late on Tuesday afternoon in a shooting at a community college in Houston, Texas that have left four people hospitalized and touched off fears that the campus had been the site of another mass shooting. 

The man is Carlton Berry, 22, and he was charged with aggravated assault but remained hospitalized for injuries sustained in the shooting.

A dispute between Mr. Berry and another man on Tuesday led to the shooting at Lone Star College’s North Harris campus, the authorities said. At least one of the men may have been a student or a former student at the college. Both were detained by the authorities. 

Three people were wounded by gunfire, including the two men in the altercation and a maintenance worker who was shot in the leg. A fourth person, who was not shot, was taken to a hospital with medical problems.
School officials said the campus would reopen on Wednesday morning on a normal schedule.

The college, which has 19,000 students, was evacuated, and Houston police officers and Harris County sheriff’s deputies spent hours clearing the buildings and deeming them safe.
Officials with the Sheriff’s Office said they received the first call at 12:19 p.m. They said they did not know what the dispute was about. One of the men in the altercation had student identification, but officials had not confirmed that he was enrolled at the college.

An official with the Sheriff’s Office, Maj. Armando Tello, said there appeared to be only one gun involved. Major Tello was the acting sheriff because Sheriff Adrian Garcia was out of town.
The shooting shocked students, faculty members and administrators at the 200-acre campus. The school is in northern Harris County and about 30 minutes from downtown. It is so close to George Bush Intercontinental Airport that college officials said one can often look up and wave at the passengers.

Students said they did not realize that the shots were actually gunfire. Because the shooting occurred outdoors — in a center courtyard near the library and academic buildings, officials said — many heard the sounds. One student sitting at a table on the third floor of the library thought it was a book cart toppling.
