A man wanted for questioning over a racist rant on a train has been urged to “do the right thing” and come forward.
Detectives are looking for 43-year-old Darren Daly in connection with the vile outburst, filmed by a fellow passenger last month.
Four addresses in the Brighton area have been searched in recent days but Mr Daly has not been found.
The video showed a man calling a black passenger a “monkey”, a “mongrel” and a “gorilla” on a train heading into Brighton.
Shocked travellers told the man, who appeared to be drunk, to sit down and be quiet but he continued, threatening to kill the frightened victim with a glass bottle.
When the train stopped outraged passengers summoned station guards and showed them the video of the man’s behaviour.
But after supplying his details he was allowed to walk free – after being given just a slap on the wrist for having the wrong ticket.
It was only when the shocking footage was reported by the media nearly two weeks later that police announced they would launch a proper investigation.
Inspector Gary Ancell from British Transport Police said: “We take all reports of racism extremely seriously and will do all in our power to trace the man responsible.
“I am urging Mr Daly to do the right thing and come forward and speak to us.
“In a bid to trace him we have visited four addresses over the past few days, but unfortunately to no avail.
“However, our investigation continues, and we are currently looking at CCTV opportunities, circulating information across police intelligence systems and to other forces.”
Anyone with information about the incident should call British Transport Police on Freefone 0800 40 50 40 or text 61016, quoting reference B7/LSA of 05/06/2013.
