"All the precautions that could've been taken have been taken," said Francis D. "Bud" Riley, HUPD's chief.
Aside from a few incidents, Riley said he is pleased with the SSI guards' performance.
"[Allen's incident] doesn't necessarily reflect on the company," Riley said.
That said, University officials released few details of the complaint or their reaction to it.
"Regardless of his employment status with SSI, he will not be allowed to work at Harvard again," HUPD spokesperson Peggy A. McNamara said.
The court will process Downs' complaint, and serve Allen with a time and date to be arraigned in Middlesex District Court later this month.
Allen could not be reached for comment yesterday.
Officials at SSI did not respond to a request for comment.
