Three people have been arrested after a mother claimed her son was circumcised without her consent.

The mom said she was left hysterical after opening her baby boy’s diaper to find him covered in blood, immediately contacting social services.

She said the boy had been cared for by his paternal grandparents in July 2013 when the procedure was carried out.

Speaking to the BBC, the mother said: “I opened the [diaper] and I ended up having to leave the room because I felt hysterical.”

She claimed her son’s health had been affected since, saying: “It looks like he’s been half circumcised is the only way to describe it. There’s half the skin, it’s not all the way over.”

“It swells up, it gets red and a little bit sore in places.”

She had contacted police but the case was not deemed a criminal matter, with human rights lawyer Saimo Chahal since stepping in and writing to police.

Cops have now reopened their investigation.

Police said three people were arrested last week. Circumcision is legal in the UK – but only if both parents agree.

A police spokesman said: “A 61-year-old man was arrested on suspicion of grievous bodily harm with intent.”

“A 44-year-old man and a 47-year-old woman were arrested on suspicion of conspiracy to commit grievous bodily harm.

“They have all been released pending further investigation.”

Inquiries are ongoing.
