Darien's Police Commission swore in three new officers and celebrated recent promotions within the department during a ceremony at the Darien Community Association on Wednesday.

Officers Christopher Nieves, Richard Flood and Dennis Sang have joined the Darien Police Department as probationary officers sharing, more than 35 years of law enforcement experience between them. Captain John Lawlor, Lieutenant Jerry Marron and Sergeant Nicholas Aranzullo were formerly sworn into their new positions which were announced on March 17.

Officer Nieves was born in Brooklyn, New York and spent three years with the New York City Police Department's impact unit, which specifically targets crime afflicted areas within the precinct. During his last six months with the NYPD Nieves was assigned to a mentorship role helping a new officer become acclimated to patrol work.

Officer Flood spent 19 years working with the Eastchester Police Department, working with the town's emergency response and traffic units and serving as an instructor for firearms and Taser devices. Prior to joining the Eastchester police force Flood began his career with the New York City Department of Corrections and the NYPD. Flood's love for the profession led him to join the Darien Police Department after retiring from Eastchester.

Officer Sang emigrated from China to the United States with his family when he was 11-years-old and, like Officer Nieves, grew up in Brooklyn, New York. He was a NYPD cadet for two years and worked with the New York City Housing Authority before joining the Connecticut State Police in 1997. While working with the state police Officer Sang became a detective in the Bureau of Criminal Investigation's Casino Unit and was later assigned to the state wide Organized Crime Investigative Task Force. Officer Sang is fluent in Mandarin and Cantonese Chinese dialects and is certified as a linguist by the FBI. He retired from the state police to join Darien's local police force.
