Yep. From wikipedia:
> On Wednesday, November 9, 2016, an underage African-American Oberlin College student and Student Assistant Treasurer,[9] Jonathan Aladin (aka Elijah Aladin), attempted to purchase a bottle of wine using a fake identification card.[8] The store clerk, Allyn D. Gibson, a son and grandson of the owners,[6] rejected the fake ID. Gibson noticed that the student was concealing two other bottles of wine inside his jacket.[10][6] According to a police report, Gibson told the student he was contacting the police, and when Gibson pulled out his phone to take a photo of the student, the student slapped it away, striking Gibson's face.[11] The student ran out of the store. Gibson followed and then grabbed and held onto the shoplifter outside the store after the shoplifter had also assaulted the store owner, David Gibson.[6] Two other students, Cecelia Whettstone and Endia Lawrence, friends of the shoplifter, joined the scuffle.[6] When the police arrived, they witnessed Gibson lying on the ground with the three students punching and kicking him.[11] The police report stated that Gibson sustained a swollen lip, several cuts, and other minor injuries.[7][12] The police arrested the students, charging all three with assault and the shoplifter with robbery as well. In August 2017, the three students pleaded guilty, stating that they believed Gibson's actions were justified and were not racially motivated.[11][13][14] Their plea deals carried no jail time in exchange for restitution, the public statement, and a promise of future good behavior.[13][15] From their trial courtroom, Assistant Dean of Students Antoinette Myers sent Raimondo a text message: "I hope we rain fire and brimstone on that store."[16]
That's not really an example of a "chase-and-detain policy", nor was it a "suspected shoplifter"; by the time anyone was chasing anyone else, it was a matter of assault.
