May led a meeting of the government's emergency committee Saturday morning, during which she was updated by police and security services on the investigation into the suicide bombing at a pop concert that killed 22 people. But when the trust between countries is breached, it harms the investigation, witnesses and victims' families. Home Secretary Amber Rudd had earlier criticized USA officials for sharing details of the atrocity with American media.
United Kingdom police have identified 22-year-old Salman Abedi as the individual they suspect of having perpetrated the attack.
The new images include what could be part of a detonator as well as a 12-volt battery and torn scraps of blue fabric said to be from suspect Salman Abedi's rucksack.
Abedi's father, Ramadan, told Reuters he spoke to his son five days ago, and "everything was normal".
But on Thursday the leaks continued, culminating in a New York Times article which included detailed forensic pictures of the crime scene outside the Manchester Arena, including the remains of the bag that Abedi used.

Meanwhile, British Prime Minister Theresa May is set to take up the issue of evidence leaks over the Manchester bombing in the United States media with President Donald Trump when she meets him at a North Atlantic Treaty Organisation summit in Brussels later on Thursday.
British officers said the leaks had caused "distress and upset" to the victims' families.
May also said "we have a special relationship with the USA". A woman who was arrested earlier was released without charge, police said.
"I think it's very clear that this is a network that we are investigating", police chief Ian Hopkins said outside Manchester police headquarters.
Abedi died in Monday's blast at an Ariana Grande concert. At least 59 other people were injured.
