New Assistant Chief Constable appointed at EMSOU

The East Midlands Special Operations Unit has announced Diane Coulson as its new, and first ever female regional lead.

Ms Coulson takes on the Assistant Chief Constable role, after Paul Gibson left to be Chief Constable of Lincolnshire Police back in March.

She originally joined the collaboration as Head of EMSOU in Autumn 2023, and has now stepped up another level to lead.

She said: “I am delighted to be appointed as EMSOU’s new ACC. I am committed to helping tackle the most serious and violent criminals in the region, and working with our colleagues to keep our communities safe.

“I was born in the East Midlands, and have built my life here. Living and working here, I am always so proud to hear of the hard work that goes on across our five police forces. Real stories of hard work, bravery, and people wanting to make a difference for our region to be a safe and happy place to be.”

ACC Coulson now oversees Forensic Services, Counter Terrorism Policing, and work from across Serious and Organised Crime (SOC), Major Crime, Case Reviews, and more, for the East Midlands.

Having joined Lincolnshire Police in 1996, ACC Coulson went on to spend half her time in uniform and half as a detective. It was in 2016 that she joined EMSOU as part of its Major Crime Unit, investigating homicides across the region.

“We have already had many fantastic results since I returned to the region last year, and I am committed to providing clear direction for us moving forward.” She said, “I’m here for the long run and look forward to working with the regional forces to support them in keeping our communities safe.”
