Two men arrested in connection with a recent incident at Kensington Gardens have been released from police custody.
Kensington Gardens was cordoned off and closed to the public on April 17, with police investigating a possible attack on the Israeli embassy after a “number of discarded items” were found.
People were evacuated from the park as police investigated claims that a group linked to Iran used drones to drop radioactive material, while police teams on site investigated the jars of a non-hazardous substance.

Two men were arrested by Counter Terrorism Policing (CTP) at separate locations last week as part of their investigation.
A 39-year-old man was arrested on April 21 at an address in Ealing under section 41 of the Terrorism Act 2000, while a 37-year-old man in Devon was arrested on suspicion of preparing terrorist acts on April 26.
Both men have now been released from police custody - the 37-year-old man was released on bail until July, and the 39-year-old man was released without charge.

Commander Helen Flanagan, Head of CTP London said: "Although these two men have been released from custody, our investigation into this incident continues.
“We appreciate the community remains very concerned about this, and other incidents that have targeted Jewish, Israeli or Iranian sites over recent weeks. We have made a total of 26 arrests across our various investigations and we continue to work to identify anyone who may have been involved."
CTP officers and the Met Police are working to provide support to a large number of organisations, community venues and businesses, in response to a number of arson incidents, over the past few weeks.
Eight people have been charged with arson-related offences and one person has been convicted of arson since the attack on Hatzola ambulances in Golders Green on March 23.
