The registration number of the car the robbers drove is ______. [originaltext]

Inspector
Interviewer: According to local news, more details are emerging of yesterday’s raid on the city’s central branch of the Northern Bank. Police have spent the day interviewing eyewitnesses and piecing together information hey have received via a special telephone hotline. We’ll be giving you that number again later in the program. Here to tell us more about the enquiry, though, is Inspector Tom Wells of Wessex CID. Hello, Inspector.
Inspector: Hello.
Interviewer: This seems to have been quite a daring raid, doesn’t it?
Inspector: Yes, indeed. The robbers drove up to the bank in broad daylight and parked right outside.
Interviewer: Do we know what kind of car they were driving?
Inspector: Yes, we know they were in a blue Ford van and thanks to a very sharp-eyed witness, we know that the registration number was BWV593 with either an A or an H at the end and I’d like to ask you viewers to keep an eye open for that vehicle and let us know if they see it. It’s probably been abandoned somewhere by now.
Interviewer: What else can you tell us at this stage?
Inspector: Well, one man entered the bank at about 3:20, leaving the other at the wheel of the van. He must have put on a mask to hide his face when he was just inside the door. He then produced a sawn-off shotgun and made the three customers who were in the bank at the time lie on the floor before demanding money from the cashiers.
Interviewer: Do you know if it was a real gun?
Inspector: He didn’t actually fire the gun of course, thank goodness, but we’re pretty sure it was a real gun and there’s no reason to believe it wasn’t loaded. The manager, who was in his office, saw what was happening and pressed the alarm bell. He then came out to help his staff to pack the money into a bag. The gunman gagged him and tied him to a chair afterwards, but he didn’t actually injure him. While that was happening, a customer managed to run out of the bank and call for help. But, unfortunately, the robber was able to grab the bag and make his escape before the police arrived on the scene. But he did drop a scarf he was wearing on the pavement as he escaped and that may give us some clues.
Interviewer: But thankfully there were no injuries. I believe you’ve issued a description of the man in connection with the robbery, haven’t you?
Inspector: That’s right yes, we’ve had a couple of pretty good descriptions of the man who entered the bank and we now also have an artist’s impression of him. He’s described as in his mid thirties, and of medium height. He’s got shoulder-length sandy-coloured hair, quite wavy, and a pale, rather unhealthy-looking complexion. He was wearing an earring in one ear and several witnesses reported seeing a sticking plaster on his face so we believe he may have a cut of some kind on his left cheek.
Interviewer: Well, that sounds like a very useful description. Do you know what he was wearing ?
Inspector: Yes. He was wearing a kind of light coloured ski-type jacket and dirty jeans with a tear in one of the knees and he had sports shoes on. Oh, one other tiling; the bank’s security camera shows hire holding his gun in his left hand suggesting that he may be left-handed.
Interviewer: So, if you see this man... what would the viewers do, Inspector?
Inspector: Well, don’t approach him. We believe he may be dangerous. If you see him, telephone the hotline on 574301 or call your local police station.
Interviewer: Thank you, Inspector Tom Wells. That number again is 574301 if you have any information which you think would help the police.
