As police followed the men, one was seen dropping a package - which contained around 100 wraps of crack cocaine and heroin.
Shortly afterwards, a man was found in Kings Gardens and, after a short struggle, he was detained by police.
A 21-year-old man from Bootle was arrested on suspicion of possession with intent to supply a controlled drug of class A cocaine and heroin, theft of a pedal cycle, assault of an emergency worker and obstruction of a stop and search.
The man was taken to a police station on Merseyside for questioning by detectives and has now been released under investigation.
Inspector Andrew Minnery said: “This arrest shows the risks our officers take every day to keep our streets and residents safe from violence, drugs and crime.
“Thankfully a significant amount of Class A drugs was discovered by our officers that could have caused serious casualties and misery in our community.
“Please contact us if you think someone could be using or supplying drugs near where you live so we can continue to take similar action and stop the spread of illegal drugs that could endanger our officers and others in your area.”
Anyone with information on drugs being stored or supplied is asked to contact Merseyside Police via Twitter (@MerPolCC) or 'Merseyside Police Contact Centre' on Facebook.
