BTP LEAD

 


The knife attack on board a train between Peterborough and Huntingdon shocked the country.  The bravery of members of railway staff and the public have rightly been subect of much praise.  The response by Cambridgeshire Constabulary was swift and effective.  The investigation, led by British Transport Police is ongoing.  (source of photograph not known)



The awful attack by a man with a knife on an inter city train, that injured 11 people, is currently subject to investigation and one man has been charged with serious offences.  In these circumstances it is not appropriate to comment in any detail on the incident itself.

The investigation is being led by British Transport Police (BTP) who have identified a linked offence on the Docklands Light Railway which has also resulted in charges.  Other possible offences away from the railway network are being looked at by Cambridgeshire Constabulary who have acknowledged that the overall lead for the investigation sits with BTP.

The ‘lead force’ arrangement is not uncommon when a series of possibly linked offences has taken place and span force areas.  It is a sensible and operationally effective way of approaching an investigation.  BTP are quite capable of performing this role and will have, I have no doubt, allocated appropriate resources.  They have access to all the necessary specialisms that may be required. – including those that reside within other forces.  This joined up approach is clearly in the public interest.  It is fairly rare however for BTP to be the lead force – an exception being – in England and Wales at least - the criminal aspects of investigations into railway accidents. where the BTP lead principle is obviously appropriate. 

There are various agreements in place to facilitate the interface between BTP and local police forces, including a Protocol (a copy of the latest version of which appears not to be readily available).  If this had been an attack that was deemed to be a terrorist incident the investigation would have, nominally, been led by the local force (according to the 2011 Protocol), but in practice by Counter Terrorism Policing.

In the case of the Huntingdon outrage BTP can be the lead force for the non railway cases if such a role is purely administrative.  If BTP require constabulary powers then the force can obtain them in various ways:

i.                    If the possible crimes are seen to be “connected to a railway or to anything occurring on or in relation to a railway.” (s31 Railways and Transport Safety Act 2003), Or

ii.                   If BTP are formally giving mutual aid to Cambridgeshire Constabulary, in which case the Chief Constable of Cambridgeshire would be in charge of the officers ‘on aid’ (s24 Police Act 1996), Or

iii.                 If Cambridgeshire Constabulary request the assistance of BTP in relation to the non railway elements of the investigation then this will suffice.  Such a request need not be in writing but is likely to be so recorded in this type of case.  A request has to be made, BTP cannot assume responsibility for the offences occurring outside the railway unless invited.  If such a request has been made then the BTP officers assisting would have all of the powers etc of an officer of the Cambridgeshire force (s100 Anti-Terrorism, Crime and Security Act 2001).

I have no doubt that this administrative issue will have received the necessary attention, so why am I posting about it?

The issue in my view is:  why is this even necessary?  Why should police forces have to turn their mind, even briefly, to this sort of arcane nonsense – especially in the middle of a major investigation?  If Cambridgeshire were asking Northamptonshire (or any other Home Office force) to take the overall lead the question of jurisdiction would not arise.  It really is time for the jurisdiction and powers of BTP to be aligned with other forces.  This will be a recurring theme on this blog I am sure.  In the meantime my best wishes are with the officers of both forces who are investigating such dreadful crimes.

It is very hard to talk about the role of NHDPFs without looking at the law.  The legal background to NHDPFs is complex and therefore I should remind anyone reading this is that I am not a lawyer.   I am certainly not qualified to offer any advice on legal subjects.  The views expressed are my own.
