Andrew Mountbatten-Windsor arrested on suspicion of misconduct in public office, BBC understandsYou shouldn't imagine this is some sign of superior British justice. Andrew is a nuke and they have to contain the blast radius, somehow, and they decided this was the only way. Important people only face consequences if it is the only way to prevent other important people - in this case, most of them - from facing consequences.
Also British law on the press and criminal cases is such that once there is an arrest, no one (the press - but with social media that means everybody) is supposed to talk about it until it goes to court. Arresting him is also a way to shut people up for awhile.
