Any idea where this beeping is coming from? I've heard it since about 8pm and know it has been heard as far as union st. I suspect it is from the shard, but seems to sound equally as near wherever you are.
I am at tower bridge rd end of se1, I can hear it here too.. it is extremely annoying. I rung the environmental health to see if hey could help. Unfortunately they must have entry to the house to see how annoying sound is. Yet if they left the office they would be more than able to hear the noise - confused by the system.... no idea where it is coming from though
I walked around the block this morning and couldn't pinpoint the location either. Asked one of the security blokes at the Shard and he said they were trying to locate it, but so far couldn't track it down. It's every 5/6 sec. Must be high up anyway.
