King's Cross was evacuated and filled with armed police over the arrival of a suspected drugs dealer on Thursday afternoon.
A British Transport Police (BTP) spokesman said yesterday: “Armed BTP officers attended the mainline platforms at King’s Cross rail station shortly after 3pm today (Thursday, 13 August) to meet incoming trains to that location.
“Some platforms were closed while this activity took place.
“At approximately 4.15pm, a 40-year-old man was arrested on suspicion of possession with intent to supply of a Class B drug. Enquires are ongoing."
In pictures posted online, armed police officers could be seen in attendance.
Some people on the scene reported seeing a man being led away in handcuffs.
The station was reopened shortly afterwards and trains resumed a normal service.
Some services ran with delays of up to half an hour following the incident.
