Police have arrested two men believed to be behind two cases of theft that occurred at a Pulau Ubin resort in May and July this year.
The suspects targeted resort-goers who were kayaking or swimming, and had left their belongings unattended, the police said on Friday.
One of the suspects would serve as a lookout while the other would rummage through the unattended bags and steal the victims' wallets and handphones. In one of the cases, the two men forced open a locker and stole the items inside.
Police Coast Guard investigators managed to identify the suspects with the help of CCTV footage and descriptions from witnesses.
One of the stolen handphones was recovered by officers from the Jurong Police Division, and investigations are currently on-going.
The offence of Theft with Common Intention is punishable by a maximum jail term of three years, or a fine, or both.
