Detectives from Lambeth are appealing for anyone with footage of the moments up to and including the loose of a crossbow bolt at the Oval to come forward.
Police were made aware at 16:35hrs on Thursday, 31 August, of reports that a crossbow bolt had been loosed into the Oval Cricket Ground.
Detective Constable Dominic Landragin, of Lambeth CID, said: "There were significant crowds watching the match and it is likely that a number of those present will have footage of the incident that could assist in our investigation.
"Although nobody was injured, this was a reckless action taken with no regard for the safety and wellbeing of the spectators or the players. It is important that we trace those responsible and I urge anyone who has footage of the incident to get in touch as soon as possible."
As a result of the incident the match being played was suspended and the ground evacuated. There were no reported injuries.
It is believed that the bolt came from outside of the ground. At this stage, the incident is not being treated as terrorism-related.
Anyone in possession of footage should contact Lambeth CID by dialling 101. To provide information anonymously please call Crimestoppers on 0800 555111.
There have been no arrests and enquiries continue.
