Police Muswell Hill area: rising crime brings court action (4,6)

I haven't cracked this one yet — but the brilliant team at Times for the Times have:

LAW (police), N TEN (Muswell Hill area – London N10 postal district), then SIN (crime) reversed [rising]. The police are often referred to as ‘The Law’ e.g. ‘I’ll set the law on you’.  Last week we had comments when Notting Hill appeared but at least that’s quite well-known outside the UK because of the popular / infamous [delete as applicable] film starring Hugh Grant. However Muswell Hill, an area of north London that includes bits of Hampstead and Highgate must surely be more difficult for overseas solvers, and knowing that its postal district is N10 is even more of a challenge. I didn’t know it myself even though I was born and raised 9 miles away. On top of all that, the solver has to change N10 to N TEN, something you will never ever see.  Definitely a clue best suited to biffing and moving on unless you are the unfortunate person on blogging duty!
