The web search results mention arrests related to illegal gambling in Hong Kong, but none of the provided snippets specifically confirm that the Hong Kong police used drones for the *first time* to combat illegal street gambling operations resulting in *eight arrests* over the *past two weeks*. The evidence is too fragmented to corroborate the specific details of the drone use or the timeline/number of arrests.

The claim specifies the arrest details (seven men and a woman, aged 53 to 76, in Chung On Estate on Sunday). While the web search results mention arrests of eight suspects in other contexts (e.g., Ponzi scams, or general raids), none of the provided evidence sources confirm the specific details regarding the composition of the eight suspects, their ages (53-76), or the location (Chung On Estate) for the gambling arrests.

The claim specifies the seizure amount as HK$420 (US$54). The web search results provide different seizure amounts and items from various raids (e.g., HK$2,480 in cash, HK$1,200 (US$154) in cash, or HK$40,000 in cash). No single source corroborates the exact figure of HK$420 (US$54) for cash and equipment seized.

The claim specifies a joint operation codenamed 'JusticePeak' conducted between April 5 and 18 by Sha Tin and Ma On Shan police divisions. While the web search results mention Sha Tin and Ma On Shan police divisions in relation to joint operations, none of the provided evidence snippets mention the specific codename 'JusticePeak' or the exact dates (April 5 and 18).

The claim specifies the exact charge: 'gambling in any place not being a gambling establishment or in a street'. While the context of the arrests is illegal gambling, the provided evidence snippets do not quote or confirm this specific legal charge for the eight individuals.
