How old is the man murdered?

Interviewer: Police in North London are treating as murder the death of a man thought to be in his forties whose body was found in a pedestrian subway in Neasden. The man leading the hunt is Detective Chief Superintendent John Day, who explains what they know of the man’s movements in the early hours of this morning.
Detective: What we’ve learned is the fact that he left the Level One Club which is a drinking club in Neasden Lane about 1: 30 a. m. , and we’ re trying to account for movements up till 2:15 because it was about that time he was found by a member of the club, an employee. He was found in the underpass, the pedestrian way, under the North Circular Road. Death was due to multiple head injuries. We understand that there may have been two girls and a man who was drunk in close proximity to the entrance to the subway, who may have seen our man walking in that direction, or any attacker who may have been following him.
Interviewer: About what time would you think that they were there?
Detective: Just after half past one to a quarter to two.
Interviewer: Then in that case the gap you have is really quite short. It’s only more or less half an hour or forty minutes.
Detective: In fact, yes, as short as that.
Interviewer: Any idea of what he was wearing?
Detective: Yes, he was wearing, in actual fact, a light-coloured raincoat, grey trousers, black shoes, collar and tie with a metal tie-pin, dark hair, 165cm, fresh complexion.
Interviewer: Is there any speculation that the motive might have been robbery?
Detective: I don’t think it is robbery in the circumstances. I’m more inclined to think there was another reason for him to have been attacked.
Interviewer: And how far away from the Neasden underpass was the drinking club?
Detective: Fifty meters.
Interviewer: And at the moment you know of no other people in the area whom you want to talk to, other than the drunk man and the two women who were seen with him or near him at some time?
Detective: Yes. The club closed at half past one and there may have been other people who left the club who went that way. We understand that there were also mini-club drivers parked in the area who may have seen something as well.
Interviewer: As it is, I take it you haven’t been able to identify them.
Detective: No, not at this stage.
Interviewer: Well, thank you very much.
