Lagos locks down to receive theresa may

I think there may be some confusion here!

Lagos is a city located in Nigeria, West Africa, and it is not possible for the city to "lock down" to receive Theresa May, as she is a former Prime Minister of the United Kingdom and not a resident of Lagos.

Additionally, it's unlikely that Lagos would "lock down" to receive any individual, as the city is a bustling metropolis with a population of over 20 million people and a thriving economy.

If you could provide more context or clarify what you mean by "lock down", I'd be happy to help clarify things for you!
