No — as of the latest reports, Prince Andrew is not in jail. He was arrested on suspicion of misconduct in public office, then released under investigation and has not been charged.[1][5]
Current status
Police said the arrest did not result in formal charges, and investigations were still ongoing after his release. Reports also said searches continued at properties linked to him, including Royal Lodge in Windsor.[2][3][1]
What the reports say
Coverage from BBC, ITV, the Guardian, CNN, and others consistently described him as being released from custody rather than held in jail. Some later headlines and social posts may be misleading, but the mainstream reports available here do not show a jail sentence.[5][7][8][10][1]
Bottom line
The latest verified reporting says Andrew Mountbatten-Windsor was arrested, questioned, and released under investigation — not imprisoned.[1][5]
