A man has been arrested on suspicion of attempted murder following a serious assault on a police officer in Essex.
Officers were called to First Avenue, Canvey Island, at about 4am on Saturday following reports by residents of a disturbance.
Essex Police said in a statement: "On arriving at the scene, one of our officers was assaulted, suffering injuries to their neck. He was taken to hospital."
A 45-year-old suspect remains in custody.
A cordon is currently in place at the location and officers will remain in the area throughout the day to continue inquiries, the force said.
Detective Chief Superintendent Andrew Waldie said: "We are taking this assault extremely seriously and it is totally unacceptable one of our officers had their life put in danger whilst trying to keep the public safe.
"I'm pleased to say the officer has been discharged from hospital and we are supporting him whilst he recovers.
"The arrested man remains in custody and we reassure the public that there is no risk as a result of this incident."
The Essex force is appealing for anyone who may have witnessed the assault, or have any CCTV or doorbell camera footage, to contact them.
