Thursday 7 p.m.: A pursuit by Los Angeles County Sheriff's deputies ended at Cal Poly Pomona's University Village, the school's apartments near the main campus, according to university spokesperson Emily Velasco.

"The suspects ran into the Village," Velasco told KPCC. "One of them was detained pretty immediately. ... They set up a perimeter around the village, and the student residents of the village were asked to shelter in place while they searched the area."

While earlier Velasco had said there were three suspects, a later social media update said there were four suspects, according to the school's social media accounts. Two suspects were in custody, with one outstanding in the University Village and one possibly in a neighboring mobile home park.

The school is asking people not to approach the University Village. Temple Avenue was also closed near the University Village.

The lockdown only affected the University Village, as there is a major road separating the apartments from the rest of the university, which is also another block away. Classes were still set to take place unless canceled by individual professors, but the school noted on social media that the traffic situation near the school was "challenging."

The school's message to students: "They need to know that they need to stay indoors," Velasco said. "Do not approach any suspects. Do not answer their door for anyone other than university police or Sheriff's deputies. And we will be clearing the village, and we will let them know when it's safe."

Additional alerts will be sent through the university's safety alert system, Velasco said, which includes text messages, voice calls, emails and desktop notifications on computers connected to the university network. Velasco said they would also be publishing updates on Facebook and Twitter.
