A body was found at Bovisand on Tuesday afternoon – around seven miles from where she was last seen.
Formal identification has still not taken place but it is understood to be that of Ms McLeod.
Devon and Cornwall Police said on Thursday investigators have been granted more time to question a 24-year-old man who was arrested on suspicion of murder on Tuesday.
A 26-year-old man who was detained at the same time as the first suspect was released earlier on Thursday with no further action to be taken against him.
Speaking outside Crownhill police station in Plymouth, Assistant Chief Constable Nikki Leaper said: “I can confirm that at this time there is no known link between the suspect and the victim.”
She continued: “I would like to reassure the public that at this time we are not seeking anyone else in relation to this matter.”
Ms Leaper said officers had been granted a warrant of further detention for the suspect.
“This warrant enables police to extend the time in which a person can be detained within police custody whilst an investigation is ongoing,” she said.
A friend of Ms McLeod told the PA news agency earlier that she believed the victim “didn’t have a clue” who her attacker or attackers were.
She said that Ms McLeod’s Airpod headphones and tobacco had been found at the bus stop where she was last seen.
“The fact Bobbi’s Airpods and baccy were at the bus stop, that shows she would have struggled,” the friend said.
Locals have been laying floral tributes close to the site of Ms McLeod’s disappearance.
Hundreds of people gathered in Leigham on Thursday evening by the bus stop where Ms McLeod was last seen to hold a candlelit vigil in her memory.div data-ob-contenturl="https://www.worcesternews.co.uk/news/national/19742265.no-known-link-missing-bobbi-anne-mcleod-man-suspected-murder/" data-ob-installation-key="NEWSQ15BEE3GLF6A6AL9EECN9" data-widget-id="AR_2"">>
A bank of flowers dotted with candles has been laid by local residents over the past few days.
Amanda Isaacs, a friend of the McLeod family, thanked everyone for coming and asked them to raise their candles to the sky for the victim.
“Shine bright up their darling,” Ms Isaacs said.
Donna McLeod, the victim’s mother, was very distressed during the vigil but was able to thank the crowd for all the love and support her family had received over the last few days.
“Thank you for doing everything to try and find her and bring our baby home,” she said.
One boy at the vigil, aged 16, had known Ms McLeod while she was still at the same school.
“I hadn’t seen her for ages and I feel really bad about that, but we used to hang around together at school,” he said.
“She was just sweet, just nice, I think that’s why it’s hit me so hard, not that anyone deserves this, but it’s just awful that it happened to her.”
