Update (5:58 p.m. EDT): It turns out the shooting started when Bachmann was serving an eviction notice on the suspect's house, according to the Dallas Morning News, though unfortunately there's still not a great deal of detail. Writes the News's Matt Peterson: "A county employee said the shooting began when Constable Brian Bachmann attempted to serve an eviction notice."

Update (5:10 p.m. EDT): While the police investigation continues, Texas Gov. Rick Perry appeared on Fox News and reiterated his support for gun rights. “When it gets back to this issue of taking guns away from law abiding citizens and somehow know that’s going to make our country safer, it’s just I don’t agree with that,” Perry said noting that he didn't yet have all the details related to the incident. “I think most people in Texas certainly don’t agree with that, and that is a state-by-state issue, frankly, that should be decided in the states and not again a rush to Washington, D.C., to centralize the decision-making, and them to decide what is in the best interest for the citizens of Florida or for Texas."

Update (3:40 p.m. EDT): Along with the constable and the civilian, the suspect in the shooting has been killed due to a gunshot wound, the AP reportsABC's local affiliate 13 provides helicopter footage of the shooting scene below:

Update (3:26 p.m. EDT): The press briefing is about to start (see below). Meanwhile, KBTX has confirmed one law enforcement agent was killed in the shooting, but revised the number of total shot down to three.

Update (2:52 p.m. EDT): Police are planning a news conference to explain what happened, which will air live on KBTX, momentarily (streaming below). What we know so far is that the incident started shortly after noon, local time, "when a man barricaded in a house, armed with an automatic weapon, opened fire on officers," according to Dallas Morning News. Police have one suspect in custody, and the situation is under control. It happened off-campus, at Highland and Fidelity streets, in College Station.

Update (2:35 p.m. EDT): The local NBC affiliate KCEN reports six people were shot, including two police officers.

Update (2:15 p.m. EDT): Spokeswoman Rhonda Seaton, of the College Station police department, which responded to the shooting, tells CNN that there are "multiple" injuries, but she couldn't yet say how many. She said the shooting happened "within a block or two" of campus.

Original: The early reports of a gunman near the campus of Texas A&M University in College Station, outside of Houston, say a shooter, now in custody, appeared to be firing from a house with automatic weapons, hitting at least two police. The local station KBTX reported that "scanner traffic indicates that at least two officers are down." We'll keep the news updated as reporters arrive on the scene. The shooting, of course, comes on the heels of the mass shooting at a Wisconsin Sikh temple on Aug. 5, and the massacre at a Colorado movie theater on July 20. This shooting took place off campus. Police told CNN they issued a "Code Maroon" out of precaution.

Note: An earlier version of this story identified Texas A&M as the scene of the 1966 tower shooting, but that was incorrect. The tower shooting took place at the University of Texas, in Austin.
